Could be;
A caliper that drags, but from a binding piston, and not the slider bolts. I had that happen when the truck would get hot only.
Or
From a bad brake line. I have seen more than one factory (the flexible black) brake line collapse inside and cause the brakes to bind.
I would jack up the truck, then hit the brakes and see if the wheels spin with the same resistance.
good luck.
