When the motor warms up to normal operating temperature it will shuts down with no hesitation or any sign. It will not start back up until it cools back down.

Hello,

This sounds like you could have a failing Crankshaft Position Sensor (CKP). Your vehicle's Electronic Control Module (ECM) AKA, "computer" uses the signal from the CKP to determine RPM's of the engine and where the engine is in its four cycle stroke. When it gets hot, like most failing electronics, it will stop working until it cools back down. Your vehicle's engine will not run without the CKP signal. I have included a diagram in the diagrams down below for you as well as a few links down below for you to go to.
