I'd have a fuel pressure test done to be sure, it isn't fuel related again. Takes 5 or 10 minutes so cost should be minimal. The other thing that comes to mind is a plugged exhaust. (catalytic converter) Quite possible on a 10yr.old vehicle.

check transmission fluid.change fuel filter and air filter.try changing up on where you buy gas .because bad gas causes problems.

I would take the truck to an autoparts store and have the fault codes retrieved from the computer. Most stores will do the scan for free. I would lean toward a faulty throttle position sensor, but that's just speculation. The fault codes should narrow the problem down. Hope this helped and best wishes.

Disconnect the battery completely, try turning the key with the battery disconnected. Put the battery back together. The check engine light should be off now..
