Do you have headers?

This condition is commonly called Heat Soak. The usual cause is High resistance in the solenoid or starter windings due to the engine heat combined with poor wiring conductivity.
If the solenoid clicks and the starter turns slowly then the problem is poor connections on the battery cables or the starter windings.

If the solenoid doesn't click then it's the solenoid windings or poor wiring connections to the solenoid.

To check for low voltage to the starter, do a voltage drop to the positive cable while the starter is trying to turn. You should see 10 volts or better.

To check for low voltage to the solenoid, jump from the solenoid large cable connection to the solenoid wire connection when the condition occurs. Be sure to set park brake, truck in P or N and ignition coil wire pulled.

post back with test results.
