Sounds like you're misfiring under load. Are you due for a tune up? I'd try that first. New spark plugs, spark plug wires, distributor cap, and distributor rotor. For future reference your truck should be tuned up every 30,000 miles or 2 1/2 years. Whichever comes first. HTH. - Jim

also when did u last change your fuel filter,a clogged filter will make your truck run rough.
