2004 F-350 no start/ no throttle response

Replaced ICP sensor on a 2004 6.0 because it had been acting up. The truck started and ran great for an hour, I took it home, shut off and re-started several times OK. I went in to finish packing for a camping trip, went out to hook up the camper and the truck would not start. I started w/ether and was getting little to No throttle response. After about 5 minutes it cleared up and was running normal again so I hooked the camper up and headed out for a 3 hour tour. The compressor hose blew off about 9 miles from camp so I continued with a power shortage. Got to the campground and let the truck idle for about 15 minutes when it quit. Had to re-start w/ether now I have pretty much no throttle response and I'm stuck in a remote campground in Mid-Ohio...can you point me in the right direction that will get me back home???

OK-I have checked everything that I have found that should be checked and got the following:
ICP voltages-brown/white wire=5.16v-key on; 5.02v run ^ gray/red wire=.17v key on; .035v run ^ blue/green wire=1.46v key on; 1.3v run
Throttle pos sensor LB/BK wire=(CT)3.9v; (WOT).5v; YE wire=(CT)1.52v; (WOT)4.1v; YE/WH wire=(CT).93v; (WOT)3.5v
FICM voltage=key on 48v; cranking 48v
Fuel pressure at secondary filter=45 PSI
The truck is a NO-START. If started on ether will run sluggish until it warms up, then it runs fine-can't shut it off or it won't re-start.
This all happened after replacing a bad ICP sensor-it started right up after the sensor was first replaced and hasn't been right since.
I'm guessing my next step is the dealer??????

Sorry to hear that man. Are you still stranded? I had similar problems and replaced my ICP but problem continued. Even though my FICM readings were good it turned out to be the cause. Maybe one of the pros will chime in. Here is a free bump to put you back on top! Keep us posted and let us know what it turns out to be.

Thanks for the info. I called ficmrepair.com and they suggested that I buy a ScangaugeII and check it or have the dealer scan for IPR duty cycle codes. I'll probably get it to the dealer mid next week because I am travelling for work.
We got home OK that week after I re-started on ether and after it warmed up it ran great. So I didn't stop and pedal down the whole way home.
