As i drive down the street in my 1994 mustang gt the car all of a sudden just shuts off like i just turned the car off then kicks right back up again. Sometimes it doesnt start up again and leaves me on the side of the road. Then i crank it to start it again and it doesnt want to start. I have to wait like 10 minutes or so, so it can be started again. I just replaced the fuel pump but it wasnt that. Any suggestions anything will help. Thanx.
