Welcome to FTE! 
The P0603 is from unhooking the batteries, no problemo there.
If that Edge thing is a chip mounted on the PCM, remove it and try again. The connections can be bad and cause problems so it's better to simply remove it while troubleshooting.
Many code readers cannot read all the codes on these trucks since they are not fully OBDII compliant. What code reader do you have? Is the CEL on?
Also, is the ICP sensor from Ford? Pretty much need to stay with OEM for that one, aftermarket parts are sketchy.
Good luck!

The truck has been put back to stock since the first try over the old programmer there is no chip it plugs in the ob II port I left the batterie unhooked for 24 hrs and this morning installed the stock program again and it fired right up warmed it up for 45 mins drove it for half mile and shut off while going down the road?

Ah, thanks for the word on the Edge unit.
Failure when fully warmed up is one of the tricks a failing IPR will play. But you have a new IPR, right?
I have heard if you cool it off it will work again. A cup of ice dumped on it, or the cold discharge from "air in a can" should cool it enough to work again. Never tried either tho.
