My car died the other day on the way home, I was turning into the intersection and hit the gas and it suddenly sounded like it was just barely holding on to the last two cylinders and couldnt accelerate, after I pushed it home I changed the fuel filter and she fired up and died after a few seconds, after another try or two she was going but I touched the throtle and it suddenly died and continues to. The map sensor comes to mind but im not sure any ideas
