Engine will not restart when hot?

Hello,

It sounds like the crank position sensor might be faulty.
A faulty crank sensor will stop spark to the plugs.

Typically engine heat and vibration can make the crank sensor go bad overtime also the wires can corrode and give faulty signals. Which will make the engine stall.
Sometimes this will trigger the check engine light, other times it will not.

Here are some helpful articles on crank sensor:

This stall can also caused by a faulty coolant temperature sensor. Which can produce incorrect signal and the engine will not start.

I have attached the diagrams for your reference.

Please let me know of any questions.

Thank you.
