Shut off while driving and will not start

Hello,

It sounds like you could have a faulty crank position sensor.
When a crank sensor fails the engine will stall, regardless of if you are driving or stationary.
Over time the heat and vibration from the engine can make the crank sensor lose its calibration and it will send error codes to the ECM and the engine will be shut down.

Here are some helpful articles on crank sensor:

Sometimes a bad crank sensor will trigger the check engine light.
Is your check engine light illuminated?

I have attached diagrams for your reference.

Please let me know of any questions.
Thank you.

Can you tell me what you have replaced so far?
That way we have better understanding of the issue.
