Alright so here is the deal. The other day i was at sonics (fast food) i shut off my car cuz the wait was a bit long. well when i went to start it back up it started but then quickly shut off again and it did this a few times before it was up and going again. so a few days have gone by and it starts fine no problems. well tonight i went to micky d's for late dinner after work and it did it again but this time it was harder to start. what could this problem be?
