I had that exact problem with my 96, turns out it was the cps...30 dollars part. it took a 10 mm wrench i believe and ten minutes to change. it is located on the front of the motor near the crank pulley. if you are looking straight at the fron of the truck, it is the 10 o' clock postion. just one bolt and one plug...my truck ran like a champ after i changed it

??
i got a 97 powerstroke and a month ago it started kinda doing th same thing i would be crusing down the road and it would lose pwer like your foot slipped off the pedal i played with the relay on the pedal and didint have a problem again but recently it started doing it again its not blowing white smoke or anythin and it only does it periodically. help??

To the guys with a cutting out problem...
My truck did this exact same thing and started about a month ago and the first thing I did was change the cps and it did it again. It was not very often but when it cut out, the check engine light would flicker on and off and the wait to start light would come on and off. I got a scan gauge to see any codes it threw and I figured out the every time it cut out and did this, the PCM was losing power and shutting down cause the gauge would go off. It ended up being the my chip was loose. Quick fix for me but was very frustrating.
Hope this might help

While Driving "Wait to Start" comes on and no power
94 f350 7.3 diesel 5-speed
I recently had my clutch go out. The flywheel was all tore up, and I replaced the clutch set and flywheel.
The night I finished, I drove my buddy home, about an hour round trip and it ran great.
The next morning, as I hit the road off my driveway I lost acceleration and "Wait to Start" light came on. It went away quickly, and I continued to go to work. It happened a couple more times.
And I noticed that it was much harder to start for the first time of the day. I have to cycle power about 4 times to get it to turn over.
Since then some times I go in spurts where it keeps doing in a few times in a row, and other times maybe just once or twice in a 30 minute trip.
I changed the Cam Position Sensor because of the advise on here. It started right up, and I picked up a pizza with no issues.
The next morning I went to go out, and it was a hard start, and it started doing it again right out of the driveway.
I notice that it doesn't go away until I release the gas pedal. It just happened to me and I tried to keep the pedal depressed to see what happened, and it continues to just slow down.
My buddy suggested that I actually got a bad CPS, but I'm not sure.

After letting truck sit for a couple hours while I posted on here and looked for answers, I started her up, and she started right up. I drove to the part store, and hooked a computer up to it. (No issues on the way)
Codes:
DTC 116
DTC 50
DTC 845
The guy helping me insisted on helping, and then got busy, so he ran off right after getting the codes.
116 is a engine temp. It is possible that it was not warm enough yet.
But that raises the question of how long it should take to warm up.
The other 2 codes, I can't find anywhere. Any ideas? I wanted to be a dick and tell the guy I was there first and he should help me, but I just left. I didn't know they are they only shop that has the old style code scanner.

EPR: Exhaust backPressure Regulator, also EBP regulator
Output; For quicker engine warm-up at cold temperatures. If the IAT is below 37°F (50°F
some models) and the EOT is below 140°F (168° some models) the PCM sends a duty cycle
signal to a solenoid which controls oil flow from the turbo pedestal. This causes a servo to
close a valve at the turbo exhaust outlet. The PCM monitors the EBP input to determine if the
EPR needs to be disabled to provide power for increased load, then reapplys the EPR as load
demand decreases until EOT or IAT rises. PID: EPR (duty cycle), EBP (pressure)

Diesels are cold blooded. It takes a while. I have an EOT gauge (Torque Pro on my Android phone) that I watch in the winter.

Since Bob has AE as I do... I think he would agree... Intermittent problems are hard to trace. I trace those by hooking up AE on live data and recording sessions. I you drive and have no problems, then you can over write the file. If you do have problems, you can see it and possibly trace it down.
You are not going to want to hear my experience of "my own" with that... It was the IDM. But you know, that kind of thing could be anything electrical and be the same symptoms. That could also be the injector wiring harness, battery cables, etc, etc, etc.
