When driving will sometimes just die?

Hello,

It sounds like there might be an issue with the crankshaft position sensor.
The crank position sensor is located toward the bottom of the engine next to the crank pulley. It measures the revolution of the engine and sends that signal to the ECM. Over time with heat and vibration from the engine it can lose its internal calibration. This will lead to incorrect data sent to the ECM. That can trigger an engine to shut down.
This can happen at any random time, and it may or may not trigger the check engine light.

I have attached diagrams for your reference.

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