01 cummins intermittent power loss

so my 01 dodge 2500 recently has been having a problem. most of the time the truck wil run just fine. but sometimes driving down the road the power will suddenly just drop off, not entirely a dead pedal, but almost there. most of the time if i push the clutch in and let it drop to an idle then the power will come back until it does it again. also if i am just sitting at an idle and i romp on the throttle it will kinda miss sorta sounds like a backfire. and when it misses it will white smoke. which is the opposite of my normal black cloud. also it threw the
P0216 code so it looks like my vp is shot. but could all this be caused by a bad vp?

thanks

How long has it been since you changed your filter? Also might be a tps sensor it can cause almost a dead pedal sometimes.. Also I seen ya have an air dog have you drained the water seperator lately I know it might be dumb questions but I work in a diesel performance shop and you'd be surprised at regular maintenance don't get done

the filter and water seperator are brand new, that was one of the first things i tried. fuel pressure is 18 at idle and doesnt drop past 16 at WOT so i think the filters are stil ok. i did also try draining the water recently with no change. i was thinking the tps as well, i tried the APPS reset and saw no difference. today i replaced the IAT sensor because i found it was very extremely dirty, no change. oh and by the way, it looks like my head gasket is blown as well. im not sure if it could be related but i am not sure.

Normally P0216 means the VP is on its way out. When mine went out I was at about half throttle and I lost power for a few seconds then it came back then I loose power again when I accelerate then it got worse to the point I had to stop driving it. And I can't even free rev my engine past 2K without out it sputtering.
