    Default 94 suburban hesitation/loss of power

    i have a 94 suburban 4x4 and after the vehicle runs for a while (city or highway) it starts to hesitate and lose power if on the highway the speed will reduce, but if i turn off the engine and start it right back up it will drive fine for a little bit and it starts hesitating again ive replaced the ignition coil and that didnt help. also if i accelerate quickly it will start the problem immediately any help will be appriciated

    I would probably start with some basic diagnostics: any codes in the computer? fuel delivery up to par? any obvious vacuum leaks or loose wires?
