Hello,

It sounds like you have a faulty crankshaft position sensor.
A bad crank position sensor can stall the engine while driving. After the stall it may or may not start back up.
Many times these faults happen when the sensor is hot due to the engine being at operating temperature, it will send error signal to the ECM and the engine will stall. Then it can start back up after everything cools.

Here are few helpful articles:

I have included the general diagnostics for the crank position sensor below.

Please let me know of any questions.
Thank you.
