Car shuts off after driving for a while?

Hello,

It sounds like you might have an issue with the crank position sensor.
The crank sensor is located on the lower part of the engine.
Over time with heat an vibration the crank sensor will loose its calibration and start to produce faulty signal. When that happens the engine will not start.
When the crank sensor starts to go bad it will fault out at random times. Typically it will fault when the engine is hot.

Please let me know of any questions.

Thank you.
