Hi rocket_61. Welcome to the forum. If I'm interpretting this correctly, the problem isn't with the engine running; it does not crank when the engine is above a certain temperature. If that's correct, and you hear one kind of loud clunk from the starter when the ignition switch is turned to "crank", suspect worn contacts in the starter solenoid. The problem is very common. It really isn't CAUSED by the increased temperature, but because the affected parts are made from copper, temperature changes can affect when the problem shows up.

If this is indeed the cause of the trouble, it will get worse as the contacts continue to wear away. This is most common on the little silver Nippendenso starters. The solenoid contacts can be replaced separately, but most people just replace the entire starter.
