the last couple days my 03 powerstroke 7.3L will be running fine than the check engine light will come on. i can hear the engine running but i can't accelerate. then in about ten seconds or so it will be just fine. it's happened a couple of times here and there, but today it happened three times back to back. any help would be awesome, thanks.

Sounds like a dirty eye on the cam sensor. $500 at ford or $100 do it your self. 3 little bolts.

My truck is doing the same exact thing, idles at a stop light but give it gas and it won't go. I pulled the codes off the PCM and it came up as:
P0122 which is Throttle Position Sensor/Switch A circuit range/perf
P0221 which is Throttle Position Sensor/Switch B circuit low input

So that might be something to look at also. BTW my truck is a 2002 F250 with the 7.3
