Hey
I, feel sorry for you, after reading your problem, but don't worry you visit the Reliable-Store they will help you for sure. Nissan XTrail
SOURCE: Engine cuts out while driving, have to restart engine then works.
Ignition system. For failures that cut out like this is a common sign of a ignition system failure
SOURCE: Speedometer, Odometer, Trip Odometer stopped working
yes the transmission speed sensor has most likely failed, to confirm this have a trouble code test run
SOURCE: ABS, traction control and hill descent warning
check abs sensors and controls for loose or damaged connections if none have vehicle scanned for fault or pending codes a part or sensor may be going bad at an auto store such as auto zone and advance auto do it for free

Things to check
Plugs;
Remove the spark plugs and read them, they should all have a dry tip and be clean from any carbon, oil or fuel.
Usually if burning fuel properly they will have a brown or whitish looking tint from burned carbon.
If any of the plugs look wet or black or dirty looking different from the others the problem is with that cylinder, change all the plugs and see if that helps, the next lease expensive thing is replacing the plug wires.If your fouling plugs ask your parts store for 1 number hotter plug ( heat range)
Plug Wires;
Open the hood at night with the engine running and see if you find any blue looking arcing around or in the wires, if so replace the wires.
Fuel Injectors
If all above looks good your fuel injectors might be dirty or one might not be working. You could try an injector cleaner mixed in with your gas
A rough idle comes from one or more cylinders not firing as hard as the others or not at all, there are so many causes for this so you have to troubleshoot with the lease expensive fix first.
Another thing is water in the gas, you can pour plain ole rubbing alcohol in your gas tank if you suspect water in your gas. alcohol mixes with the water and makes it burn instead of mis firing.
Valves
One more thing that can cause rough idle is your valves, this requires a compression check on each cylinder. If one cylinder has less compression than the rest remove the compression tester and squirt some engine oil in the cylinder then re test, if the compression increases it is bad rings or a bad cylinder bore, if not it is a valve problem.
Oil seals around the piston increasing the compression temporarily while testing but makes no difference in testing if the valves are leaking.
Good Luck,... troubleshooting and patience, or a good mechanic is the solution if you are working with neither

Hi.
If problem is only on startup and when idleing, then the problem is likely IAC system, also a vacuum leak will cause the same problem.
If problem is not only on startup and idle, but also when driving, then MAP sensor and EGR system must be checked.
Check also accelerator cable state and setting.
The first thing to do is pulling out the OBDII fault codes stored in the ECM. This is done connecting a code reader to the ECM diagnostic port. The job can be done for a small fee at any local garage, and it is done for free at AutoZone.
The codes will help locating the problem.
About possible faults:
Problem is stalling when idling and during startup, but engine idling fast all the time. Problem not starting at times it is due to the fact that the wrong mixture is being sprayed, this is probably causing flooding and misfire. Since the CEL is on, one of the codes returned is probably misfire.
Check accelerator.
Check IAC system. This is composed by a valve and a solenoid that check and control amount of extra air air when the engine is idling. The IAC valve is located on top of the throttle body.
Check the vacuum system and try cranking with gas tank cap off. Vacuum
system is tested using an hand tool gauge onvacuum lines while spraying
card cleaner on the hoses (or heating them with a torch). If there is a
leak, pressure will go up. A big leak will also do hissing noise, and
will often result in a lean code when doing an OBD code scanning.
This kind of symptoms can also be caused by weak wiring to MAP/MAF sensor (MAP in this engine).
If the car also drives very rough and is revving up and down in a weird way, check the EGR valve.
As first thing I would do a code scanning. This car is OBDII. The scan can be done for free at the nearest Autozone, or for a small fee at any garage.
If you get any OBDII code from the scan, report it here, so that we can individuate the possible reason for the problem.
If you repute my solution helpful, then please take some times to accept the solution. Providing good repair tips requires time and skills, and your feedback is important for us.
Regards.
Ginko.

Sounds like a weak fuel pump to me. Have it pressure tested.
