03 Durango acts like it's running out of gas
I always wondered why alot of TB's get all dirty and gummed up? My TB is as clean and shiny as ever. Worst case scenario for me is the plates were just slightly coated dust. Nothing more.
Then again, I always keep my PCV valve clean and operational to help prevent my TB from getting gummed up. I only use about a couple short squirts at most of tb cleaner just to clean off the throttle plates every 30k or so miles.

I wanted to give an update. It has been three weeks and the Durango has been running great. I don't want to jinx myself, but I think cleaning the TB and IAC valve solved the problem. Thanks to everyone that helped. Saved me a lot headaches.
You can test the tps with a dmm. unplug the tps connector and hook the meter up in the ohms setting (omega symbol) I do not have any specs in my manual for the resistance specs but they resistance should sweep evenly from closed to WOT. Just move the throttle smoothly and slowly to check it, any big changes in resistance at once will indicate a short or open in the rheostat. Check your fuel pressure as well optimally when it is dying on you. At the very least open the schrader test port to see if you have pressure while it is doing it. Intermittent problems are a PITA. It could be any number of sensors, a failing fuel pump, a bad connection, something plugging the fuel pickup tube intermittently, failed gas cap, etc.
