Engine/Transmission (1994 - 1998) Truck Stalls

[Breed]

I have a 1998 12 Valve Quad Cab Cummins Diesel truck with a Automatic transmission with 107000 miles which I bought brand new. It was a California Truck and I converted the EGR manifold when I moved to Nevada 13 years ago. The truck has always run great and had a starter problem and replaced it with a Denso with bigger contacts. It has a Pac Brake. Just recently the truck stalls once in a while. It does not die but when I come to a stop and hit the gas pedal it just won't go anywhere and kind of makes a Duh sound. It seems to be getting a little worse. Usually I shut the truck off and restart and it runs just fine. Any Ideas?
Thank You,

Is the engine idle low? It should be at least 750. The oil pressure sending unit can sometimes cause that problem. Look at the oil pressure gauge at a stop. If it falls to 0 its bad.

Sounds like trans!

I checked the Oil Pressure when it did it and it remained fine, it like someone covered the intake, it just won't go, once I turned it off and then back on it ran just great. Really weird.

I think I have figured it out, I think that the Pac Brake is sticking on every once in a while. I have kept the brake lubed but the truck gets very little use. I contacted Pac Brake and they are sending me instructions for cleaning the brake.
Thank You!
