Truck will start but shut off 20 minutes later and not start again for a long time.
Do you

Good morning,

When it does not start, can you check the fuel pressure to be sure the pump is working?

Can you check for spark to the plugs as well?

It won't start after it gets warm, you can start it everyday for about 20 minutes then it will shut off and not start again. The sparks are good.

Okay, got it.

You need to test the fuel pressure when it will not start.
