Hello,

This could be due to a faulty crank sensor or a coolant temperature sensor.
The crank sensor can go bad over time with all the heat and vibration and that can trigger an engine shut down. You may or may not be able to start it back up.

The coolant temperature sensor can send error code to the ECM and the computer can think that the engine is 'too hot' and it will stall the engine as a protection. Sometimes on this the engine could start when it cools down enough.

Is the check engine light illuminated? Sometimes when you have faulty sensors the engine light gets triggered. If it is illuminated, then have it scanned for code(s). It can help with the diagnostics.
