[Mustangboy89]

i was driving my mustang and all of a sudden it just quit and i pulled off the side of the road and it cranks fine it just won't start and i waited about 45 minutes and it started up again and then i was trying to get it home and i was half way there it quit again on me and i had to wait about 30 more minutes and it started up again i finally got it home i was told it might be the coil going bad so i put a new coil on there and i check to see if my fuel pump was coming on and it's fine also (it has a 190 fuel pump in it)and i took it out again for a drive and it did it again i have no clue on what it could be.but any help would be appreciated thanks.
