I have a dodge that cranks and drives, but then will quite. I have just replaced the fuel pump. still not working right. SOmeone said it would be the shut off relay and to switch it out with another...I did...and it seemed to run better..but still dies after awhile...so someone else says its the ignition module. when it dies, it will turn over, but wont start...until you give it about an hour or so, then it will crank...I can get to work ...then in the eveing I can get home..but nothing else. Any suggesstions?

 

What year, engine size, automatic or manual? How long will it run before it does this?
