not sure the fix, i have same issue and it seems to be coming from the little round "part" near the air box on right side of motor. There is a few vac hoses coming off the part, a throttle type cable, as well as a harness type connector. I was having a similar issue, the car runs for a short few seconds then, an electrical short type of sound comes from that part and then engine stops. Can't figure out what the part is called but that is the problem part.
