Engine intermittently shuts off

Hello,

Just to clarify, regardless of if you are driving or at a stop the engine will shut down?

One of the possibilities is a faulty crank position sensor. The crank sensor sends the engine rotation data to the ECM. Over time heat and vibrations from the engine can cause the sensor to lose calibration and that will trigger error data sent to the ECM. Which can cause the engine to shut down.

Is your check engine light illuminated? If so scanning and retrieving the code(s) can help with the diagnostics.

I have attached diagrams for your reference.

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