this is why all new dodge trucks are sold with a puppy, no one should have to walk home alone.

Yep, I don't go back to work till Tuesday, hopefully I'll get it figured out by then.
 
When you take out the key from your truck and put it in your pocket, does your pant go down to your ankles? :-)

All kidding aside, the symptoms are indicating worn ignition switch. If you carry janitors key ring, then that would be most probable cause of worn ignition contacts. On some vehicles, the contacts just burn out after a while e.g. my Honda Odyssey, it was covered by safety recall.

Another point to look for is if you have any after market electrical stuff on the truck such as alarm or remote start.

When the engine cuts out on the highway with no warning and can be restarted easily, the logical culprit is the ignition system.

Your EGR codes can be ignored while you are troubleshooting this problem.

I never have trouble starting it. Wouldn't a worn ignition switch show symptoms when trying to start it?
 
Dodges used to have a master relay called the auto-shutdown relay. Usually same as the horn relay so you can swap them. This could be your problem if you still have one, but would help with ignition switch wear. But yeah jiggle the key when it's running as a quick and free test.
 
I changed the EGR valve and drove another 20 miles with no MIL light coming on or incidents. Hopefully that was it, thanks for the help guys.

I didn't. I just checked to see what that was and the price when eljefino mentioned it as a possibility. But no, I just changed EGR valve for now and seems to be doing the trick.

I never had problem starting the vehicle with bad ignition switch. It randomly started cutting out on the road and eventually frequency started getting more often.

Because in my experience a stuck EGR just makes a "cammy" idle and doesn't cut it off going down the road. Glad OP got it fixed. And a crank pickup is one of those "no code" things that can drive you crazy.

The obverse, of course, is reasonable, that the recent CEL probably held an important clue.

Probably not on a 2004... they phased it out after going to OBD-II. Too bad, it was such a neat feature.

On older Mopars where the odo is still mechanical so it will flash the "check engine" light to output codes. A burst of flashes is the first digit of a code, then a short pause, another burst of flashes is the second digit, then a longer pause, then the first digit of the next code, etc. "55" will be the last code.

Works on my step-Moms '04 Ram 1500. Ive also used it on a late 90's 3500 Cummins.

Yeah, its kinda random when it got phased out- I guess it depends on when the software was last updated for the particular vehicle. It definitely doesn't work on my '99 Cherokee or wife's 05 PT.
