Will not restart have to let it cool off then it will start

Good morning.

When the engine will not start, did you check for fuel pressure? If not, I would start there to be sure the fuel pump is delivering correct pressure. If you do not have a tester, you can rent one at a parts store.

Can you hear the fuel pump run? You can try to spray some starting fluid in the air filter and see if it starts and stalls. That will confirm fuel delivery.

Try a new fuel pump relay.
