2003 F250 7.3 Vibrates violently and has no power

[gapeach00]

I have a 2003 Ford F250 7.3L Powerstroke Diesel that has had an intermittent problem for several months. It started with the check engine light coming on occasionally when making it go into passing gear or driving it over 80-85 for an extended amount of time (ie on the interstate). No rough engine, no reduced power. Just the check engine light on. These are the codes it was throwing:
P1211-ICP out of range (above or below desired level)
P1247-Turbo Boost Pressure low
P0603-IDM KAM Module

This has progressively gotten worse. Now, when you try to go over 50-55 mph or attempt to make it go into passing gear, it begins to shake and looses power to the point that it completely stops and shuts off. The check engine light does not come on when it does this. If you let it sit for a few hours or until the next day, it will crank back up, but will start with the same symptoms after the engine warms up. This is what we have replaced so far:
HPOP oil sending unit
ICP Sensor
IPR Valve
MAP Sensor
Fuel Pump
Fuel lines and O Rings
Fuel Filter

Any suggestions??
