I have a different engine, but when my TPS throttle position sensor went belly up, it acted exactly as you are describing. And it happened without warning.
If you look at the throttle pedal, it will be a small squarish box with wires coming out of it. Usually held in place by two screws.
You should be able to find one at any truck supply house or Cummins shop.
When I had this problem in the middle of nowhere Alaska, I was able to temporarily fix the issue by using percussive persuasion on the sensor. It worked for a while longer. It’s a simple disc and wiper inside like a potentiometer. My point is that if you tap on the TPS aggressively and the throttle starts to work, then there is a good chance you have identified the problem. If that does work, I would still replace the TPS before driving any further. There is a TPS calibration procedure for some engines. Google will find it for you with the correct search terms.
If you clear the codes, do they come back?
