i was driving the other day and my car shut off out of nowhere. i tried turnin it on a couple times but didnt work. i waited about 5 min then it turned back on and i drove it home. as soon as i got home it shut off by itself now everytime i turn it on it shuts off very couple minutes . i dont know what the problem could be im thinkin maybe fuel pump but i honestly dont know does anyone have any suggestions??
