If I drive my truck for 5 plus minutes then turn it off it won't start. No crank, all electronics come on. Once cooled off it starts just fine. Only happens when it is hot outside I never have issues when temperatures are cooler. I have replaced the starter, checked for corrosion, swapped relays, and checked fuses. Like I said it only happens when hot after driving.

Good morning,

I would start with checking the battery and the connections. A weak battery or dirty connections will cause this issue.

I would also check for voltage to the starter solenoid when it does not start to verify the available voltage.
