when stopped at light/sign then try to accelerate the truck will not accelerate only about idle speed but if you turn the truck off then turn it back on it runs fine and this is an problem that happens only sometimes . the defrost also recently stopped working along with the heater it works when it wants too.
 
Have you checked the fuel filter? This sometimes causes the engine not to rev high rpms but if it still sometimes does then I wouldn't know what the problem is.
 
most likely a TPS throttle position sensor issue. They get gummed up and may stick.
you can rent a tester to check the electrical. Another option may be the egr silionoid. It will cause that exact thing in the early stages of death.

goodluck
