I have a 2004 dodge stratus with a 2.7L v6 multi port fuel injection. The car will run fine for a week to 3 weeks then all of a sudden you will shut it off to go in somewhere and when you come back it will start and die start and die over and over i have to let the car sit for up to a day before it will start and stay running and then it will run for another week or so then do the same thing. I have changed the fuel pump and the map sensor i was wondering if anyone had any ideas what this could posibly be it would be much helpful
