Then test the TPS sensor its fairly easy. Could also be your fuel pump itself dying.

all cars need 4 things......air....fuel.......spark......compressi on.......when one of these are missing it will not start or shut off rite after......check the signal going to the injectors.....check your vaccume hoses....any litle hole will make it to lean and will shut off....

Could be connection problem because it the car start then the engine o.k. Could be not getting it proper fuel from the pump..
