Ok so I finally get my car back from the shop. I'm driving her soft, gradually driving rough. As i'm driving on the off ramp my engine starts sputtering and then dies. I press the start button, she turns on, starts sputtering again and dies. I checked my battery connections, intake, loose wires, and any leaks. Everything in great so I try to start it up again, and again it starts, sputtars and dies. I try giving it gas when it starts but no acceleration, no nothing. Any Ideas to what this might be
