truck does not start immediately after driving, but will after sitting 40-45 min. Why?

What is your question?

Battery, alternator, and starter all testing as good…. Installed new Ignition switch, new battery ground, new fusible link, and new battery... Truck drives absolutely fine with no problems whatsoever, but will not start immediately after being driven……. Will start after sitting for about 30 to 45 minutes... Every time... I am at a loss.

What makes this problem better or worse?

sitting for 30-45min engine will start
