Hello,

This sounds like the issue is a faulty crankshaft position sensor.
The crankshaft position sensor mounts to the engine block below the generator, just above the oil filter.
Over time with heat and vibration from the engine the crank sensor can lose its internal calibration. This will cause it to send incorrect data to the ECM. Which can trigger the engine to shut down. When this happens, the engine may or may not be restarted.

Here are couple of helpful articles:

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
