My 1995 Chevy 1500 350, 5.7L is sputtering and dies while driving. It idles fine and while in park I can rev the engine without any issues. As soon as I put the truck into gear and press the accelerator the truck sputters and dies, but will start up without any issue. I have checked all fluids and change plugs. There is not fluid or air leaks that I have seen.
