Dodge cummins problems

I've gotta 2002 dodge 2500 cummins with a 6 speed tranny. Long story short got it at a heck of a deal from my cousin. I recently replaced the lift pump because that's what the guys in his shop said was wrong..

Well now when I am driving it just all of a sudden loses throttle. It'll hold the rpm's it was running when I experience the loss. And will idle down just fine and pick right back up to the same rpm's but no higher. You can throw it to neutral and it'll rev up just fine. Put it back in gear and it won't pass those rpm's that it was running.. And then all of a sudden it will pick back up.

It's like it also won't spool the turbo but that might be part of not turning high enough rpm's.

Any ideas? I am thinking the throttle positioning sensor or APPS

Sounds like a dead peddle issue. You can look on cumminsforum dot com. There is more info than you will need on that site. Helpful site for any cummins related trucks.
