The initial problem was the truck stalled and died. The following parts have been replaced: spark plugs, wires, fuel filter, distributor, cap, rotor, pick up coil, map sensor, throttle position sensor, and idle air control valve.

The truck starts and runs fine at highway speed but when accelerating, the truck hesitates and feels like it is "bogging" down. There are no diagnostic codes (except 12) from the computer.

Any help would be appreciated.
