Won Start Need help!!!

[Wardamn7.3]

I have a 2002 f250 and yesterday was driving at 50mph and the truck lost power and as i slowed down it cut off. I had it towed to a local shop i use and their code reader said Can not establish communication. I went out before i was going to tow it to the dealer and it started. I drove it straight to the Dealer to had them test it they scaned it and came up with this: Needs new ICP sensor and connector, IDM (which was replaced 3 months ago), and GPR. What I'm asking is could i replace the ICP and Glow plug relay and have a truck that will start and run even when it gets hot? it will only start when cold and wont run long.

Sorry for the lengthy post i am just at a loss.

Im thinking the IDM isnt bad it is just these other problems faulting it.

PLEASE HELP!!
