Singer machine problem
First thing to do is take out the bobbin and bobbin case, there may be a small piece of thread jammed holding the machine back, if it is still tight after that oil with WD40 on all moving parts, if that fails it will be a shop job.

Sewing a straight seam will be going well until
Hello,
Here are some solutions to try.
* Increase the upper thread tension on your machine. It may be too loose.
* Decrease your bobbin tension if your sewing machine allows you to adjust it. Consult your manual.
* Reinsert your bobbin. It may be inserted incorrectly.
* Change your thread. If your upper thread and bobbin threads are different types, try using the same thread for both.
Although you did this, it won't hurt to re-check. Make sure bobbin is threaded correctly.
Hope this helps.

Under fabric bunches of thread and the needle stops after seconds
Please TRY the solution BEFORE giving your considered rating.
Specific detail on bobbin case adjustment (with picture) near halfway down reply, the remainder will help you achieve a balance of top and bottom tensions.
Ensure that all is clean and free of lint and jams, this is the most likely cause....now for tension troubleshooting .......
This solution is for tension problems...if you cannot form any sort of stitch, the issue is quite different, so please let me know if you need a different problem solved.....
It is quite long, but just work through each section in order.
The "knotting up" can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.
QUICK SUMMARY FIRST:
Ensure sharp new needle,
Thread guides and Bobbin are Clean & Clear of lint
Set Top Tesion to 4 ....then....
Balance Bobbin to suit.
TOP THREAD TENSION:
If the looping threads are on the underside as you sew, it is the top tension. Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your projects).
IS YOUR NEEDLE SHARP ?
If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one !
TOP TENSION & GUIDES:
Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and not to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp.
It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically.
If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread.
Now, with a 2" (50mm) wide strip piece of fabric 8 - 10" (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with a see saw / to and fro action.
In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to disengage tension plates).... do not gouge or score the plates, they need a polished surface to work correctly.
BOBBIN TENSION:
Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a "false" tension.
I would not recommend fiddling with bobbin tension without good reason, it may end up with missing small screws and spring pieces, however, you can take the needle plate off to clean
the hook race area (where bobbin case sits)
...this is just good housekeeping, my wife does this every time she replaces the bobbin....
just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint. If there is a significant amount of lint, use a vacuum and small brush to get the worst.
Then wipe all this area with a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit, especially if there appears to be fine dirty deposits....oil and lint combine to conspire against you.
If it seems likely that you ......really ....do .....actually .....need .....to adjust the bobbin case, first check there is no lint trapped in the metal spring where the thread is tensioned.
TOP LOADER:
Drop-in Bobbin case will look similar to this image with the tension screw in the middle of the metalwork....
...the other screw at one end is holding it all together, so beware....it is not a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out !
FRONT LOADER:
....this is a bobbin case from a front loading machine and works in a very similar fashion to the top loader with drop in bobbin, again, if you dismantle it, take care so you can put it all
back properly.
FINISHING UP
GETTING THE BALANCE RIGHT:
When you are certain there's no trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.
Try using good quality thread of contrasting colours so you can more easily spot the changes.
Set your zigzag to one width less than maximum (eg. 5 of 6 ...or... 4 of 5 etc) and sew a sample for a few inches and check the result.... adjust the bobbin tension screw very little at
a time, perhaps 1/16 of a turn.
You may find you are playing with this balance for some little while and if you are putting the needleplate on and off each time begin to think it cannot be correct to do this.....BUT....it is,
and eventually, you do get a "feel" for the correct tension and then it happens quite quickly.....as a user you won't be doing it very often unless there is lint built up (or are there small hands at work around the house !?!?!)
OTHER ISSUES:
If you live near the ocean as we do, salt air can play havoc with metalwork inside and out, so to help minimise this, keep a few small packets of dessicant (silica gel) in your machine
case....no case ? then make some sort of cover !
Same applies in any damp or humid environment, keep your machine dry and dust free.
Budget for a proper full service every couple of years (more often if heavily used) and if you don't use your machine for a few years, be aware that old oil will dry out and combining with
dust and form a "clag" like glue (another reason for some sort of cover, even a teatowel !)
FINALLY, A WORD ON THREAD:
If it is worth spending the time, energy and money on making something that you would like to give lasting enjoyment......use quality thread, .......it may seem to cost a little more at the
time, but the results, ease of use and added longevity will be worth the extra, and as a bonus, your tension troubles may be fewer and further between, because there is a more consistent diameter with good thread, and less compensating to be done by your tension plates and less thread breaks

My singer touch & sew suddenly didn't stop
There might be something jamming the petal open so it won't slow or stop when you put your foot on it.. I would try that, get some canned air and blow it out and see if it helps.

Thread bunching underneath
clean the lint out with canned air and check the bobbin holder for any possible needle pieces from breaking a needle maybe the needle is bent and you can't see the slight bend.may need oiling too

slide open metal plate, there is a little white finger button with a target symbol on it just to the left. Slide this all the way left, leaving plate OPEN. If your top needle is threaded correctly, you should now be able to push the foot pedal to sew adn the bobbin will refill. make sure not to go past the outer white line on the bobbin case. good luck. the target button will go back to the original position when you slide the plate closed.

Singer 1120 timing
h,
Timing" is the alignment of the needle at its lowest point and the hook on the bobbin case. The point of the hook must pass directly behind the "scarf" of the needle fo the interlocking loop of a "single needle lockstitch" machine to occur. Look closely at the needle. You will see the long groove along the front of it. This is where the thread rides as the needle goes up and down. If you look at the back of the needle you will see a flattened area just above the point. This is the "scarf"; it's flattened to permit the hook of the bobbin case to run right by it and catch the loop.
When a machine is out of "time", the hook is either too early or too late, OR to far away from the scarf to make the connection. You can send a machine out of time by hitting a pin, or breaking a needle "hard" (too fast through too many layers, etc.). You can usually identify a machine that is out of time by multiple skipped stitches at high speeds, or by stitching fast and then quickly putting it into reverse. Sometimes, you can scrape by if you rotate the insertion of your needle a little bit, this can help compensate for minor timing issues.

I have a singer model
Have you checked your bobbin, mine sometimes gets the needle thread stuck underneath the bobbin and it all gets really tight and won't let the needle go down enough to sew.
