MAJOR loss of power within seconds of turning on!

Like the title says, its my dads 02 f250 of course 7.3. the truck is bone stock. no serious problems except minnor wear and tear. I just got home from working and my dad was out in front of the garage with the hood open...anyway he said he went driving down the road about 3 miles and the truck just like almost died on him, rpm's dropped below like 500 and if you gave it any gas at all the rpm's would just go up but the speed would go nowhere at all...the truck has about 160,000 miles on it. my gut feeling is that it has an injector problem or hpop...oh and the check engine like comes on. but he said as he was still driving wihle all this was going on. just as quick as it started it would go away and the truck drove like it was supposed to. but as he was coming back into the neighborhood it started acting up again and he had to basically limp it home. so i went and looked at it and i cant really tell just by looking at it but i went to start it just to see how "rough" it was and as soon as you start it it idles fine for about 5-10 seconds then starts kickin and running very rough. and that leads us to where we are now. Are my thoughts maybe correct on what it could be??? i would really like to pull the codes and see what they read but i dont have a scanner handy right now...what do you guys think? would really like know what what new part we're gunna have to price out Thanks
-Jon!

Sounds like it is starving for fuel. Check your fuel filter and if your below 1/4 tank of fuel try adding some more.

Fuel. UVCHs. CPS.

I was gonna go UVCH.
seems like electrical if it will suddenly do it then suddenly stop again.
a bad connection somewhere.

Don't rule out a flaky CPS. should be a code set

can you guide me to where im going to be looking for the UVCH? and where i might find and what plug it may be to see if anything is cracked...the truck is an 02 250 if that would help you be able to tell me where to look. Thanks guys!

Pull both valve covers and you will see your problem, there will be a melted wiring harness or some broken wires, i almost promise you. i was once in the same predicament and i damn near thought my truck was gone over a 50$ part.

Under Valve Cover Harness (UVCH)
