I have company service truck it's a early 2006 F450 with the 6.0 in it.
I was getting on the freeway and by the time I got the the next exit the engine had shut off, no warning, no check engine light, it just stalled out.
It cranks good, checked for fault codes there are none
Checked the fuses they are all good
Also I need a diagram for the fuse panel
To me the way it's acting is the injectors don't want to fire.
If I could get some help with this it would be great thank you.

You need a way to look at actual numbers while cranking, I use a snap-on scanner. There are far too many things on those that can cause the issues you described for anyone to give you a good answer.

Things you can try without a scanner, is to try starting it with the ICP sensor unplugged. Then I would test the fuel pressure.

Most everything after that will will need a scanner.

If you end up convinced it is the FICM, have it rebuilt and upgraded at either FICMRepair.com or CircuitBoardMedics.com. It is cheaper and better than buying a new FICM.

Sadly, sending in the FICM is the only way a logic board can be tested.

The FICM can cause intermittent stalls, but so can the IPR (or its connector/wiring).

Several other less common issues can cause it as well (shorted injector coils is one).

Since you posted that you checked for codes, what are you using as a scan tool (because MANY scan tools do not read codes thoroughly)?

FORScan is the best and the cost is low.
