My 2003 Ram 1500 4.7 runs and drives great for about approximately 7miles or so then just dies no warning, try and restart but only cranks, wait about 2 to 3 minutes and it restarts and might go a mile or so before it dies again, wait 2 to 3 minutes and restarts, longer I wait the farther it goes, replaced with new fuel pump and filter but still dies after a few miles, any suggestions, Recore

Not familiar with a 03. Doesn't sound like fuel problem but electrical. Something is overheating under the hood and falling but works when cool. Check all ignition system parts.

Have you verified battery isn't swollen and overheating? Sensor in battery tray measures batt temp, notorious for giving trouble, shuts truck down if detects battery overheat/fault, have battery checked/tested, also check codes and see if you see power fail code in ecm or battery disconnected code....could be bad ground to body causing ecm to "blink"

And one other, the monstrosity dodge calls the ignition SWITCH is also known for intermittent contact, not the key cylinder, the physical switch on bottom of steering column, 1st symptom is ac/heat blower working intermittently, easy and cheap to replace but open the old one and look at all those archaic finger contacts that belonged on the Nina pinta and santemaria with Columbus......good trucks but somebody really needs to strangle the design team

Do you smell gas when it shuts down? That would be an indication of no spark, and flooding. Black smoke when it restarts? Also too much fuel, no spark. If there no signs of flooding, it is more likely fuel starvation.

I had a '79 Buick with similar symptoms. Tried two fuel pumps (low pressure system, the car had a carb), fuel filter, no help.

Long story short, I wound up dropping the gas tank, taking the fuel pickup out, and soaking the 'sock' on the end of the tube in lacquer thinner. The lacquer thinner turned dark, it seemed to wash off lots of buildup that was restricting the flow.

Put it back together, never had another problem with it.

Sounds like the cam/crank sensor fails when it gets hot they are both cheap to replace or have someone with a good scanner hook up to it and verify.
