After the truck has been driven it will not start back up when hot. It won’t even crank. I’m at a loss.

Most of the time this will be the starter motor, or the battery cables need to be replaced. This guide can help us test for power at the starter trigger wires which will help us confirm the failure:

This video can help as well:

Here is the starter location so you can run the test. Check out the images (below). Please let us know what happens.
