    1996 chevy 4x4, the truck cranks and runs fine until i reach 50 mph, then it spits and sputters and wont go any faster, i shut the truck off and wait a few seconds and crank it back up and it runs fine until i get to 50 mph. the truck also takes a long time to shift between gears, to my knowledge there is not a shift kit installed in the truck. Any ideas?

    Transmission fluid change maybe?

    may be for the shifting problem, but what about the rough running at 50 mph

    When was the time you changed the fuel filter?

    Yep, I agree, a clogged fuel filter will make your truck fall flat on top end and spitter and sputter.
