loss of power?

2001 F350 7.3 manual trans, no add ons. I have replaced the ICP, CPS and MAP and just last night rebuilt the turbo, kit came from Ron's. Oil and filters all changed within the last 1500 miles. My truck will start, warm up and start out good no CEL, after about 20 seconds to minute the CEL will appear and no power. I mean it won't pull it self up the hill. I can turn it off and restart with the clutch and it will run fine for the same amount of time, once the CEl appears no pwer again. The turbo doesn't seem to spool after the CEL comes on.

Any ideas would be greatly appreicated.


thanks

Once the CEL appears there is no throttle response. If I restart the vehicle the CEL goes out and all power is restored, but not for long....BOOM CEL on and no power.

You might have a bad TPS (throttle position sensor). I had that happen to me and it would only idle and the CES would come on when I pushed the throttle.

The part is not that expensive, but I cheated. I removed it from the pedal, drilled a tiny hole in the casing, and sprayed that sucker full of contact cleaner. Hasn't happened since.

I'm also following this post same thing happened to my 99 F-350 7.3
Starts fine but as soon as you take it over 1500 rpm it shuts down had to limp it home
hardly made it up the hill.
I'm being told it will be the 7.3 Cam sensor but this sounds more like it

You need to get a scanner on it and see what code is being thrown, no sense throwing parts at it.

the cam sensor doesn't cause loss of power, it causes random shutdowns. the pedal position switch might be causing this. i had the same problem years ago with my 7.3L. ended being the Injector driver module (IDM) was dying.

I agree with doc. If u are going to buy parts run codes first. My suggestion would eliminate a possible problem without costing you a part.
