I have a 2003 mack, that keep dying. It will run for about 3 to 4 hours after that time frame, it will die. You can wait for 15 to 20 minutes and it will start and run for a hour or two and die again. Can anyone help me with this problem?

I wonder if your fuel tanks are breathing?Loosen the fuel caps and try it,you should here them sucking air more than normal as you loosen the cap.It does sound like the fuel system is not breathing properly.Ron G
