Sounds like you might have a bad tps. If it were the transmission I believe the rpms would rise normally.
Dead spots in the tps could cause your problem I believe. When you notice the rpms not responding
is the truck still pulling hard?

Now it sounds like a torque converter, transmission problem. You might have to take it to a
transmission shop and let them diagnose it.
