Runs fine but only runs for 5 min then shuts off for 5 min then back on, will not stay running.

change the oil to the correct specification first. As the engine runs the heat changes the viscosity and overheats or trips the oil alert switch. If its over 10 years old change the oil alet magnetic switch

Sounds like the module inside the distributor. Have to be replaced.

It's one of two things. My first thought is that you have a clogged gas cap. Try loosening it when the mower starts to run ruff. If it smooths out again and runs fine, then you know that the carburetor is not venting properly. Either buy a new gas cap or clear the breathing holes in the cap, if possible.

The only other thing it can be is that your Ignition Coil is going bad. A bad Coil, once it gets hot, will shut down. But it usually takes longer than 5 minutes for them to cool down well enough to start back up.

My Vote is the cap!

Good Luck!

HAVE YOU CHANGED THE PLUGS AS A FIRST STEP

run it without the filter with a 1 part vinegar 4 parts water. then try it with a clean or new filter. You may need to run it a few (5-6) times before it stops shutting off by its self.

You may have a cooling problem (with older computers), if you hear your fan running excessively and then it shuts down on you. Otherwise it is more likely a hard drive issue.

a bad crank sensor can cause this. shuts off while going down road, and will start about 10 min, later with no problems runs fine until it quits again. hope this helps,

dryer was working with codes for 5 to 10 min now there is no heat at all but will stay running?

check the photo eye. It's the little rubber boot on the bottom right on the back side of the burner. If it's dirty, it may not be shutting off the igniter. If the igniter runs continuously, the safety breaker will trip.

check for proper pump pressure. Restricted fuel flow. Proper venting of fuel cap.
