trouble starting, sometimes.
 

06 F250 6.0 with only 65,xxx miles on it. This has happened twice and both times the engine was warm and had been cut off for less than 10 min.. When I tried to crank it back up it stumbled and idle roughly then cut off. After several attempts to re-crank it still would idle rough and I tried to give it fuel but no change, even with pedal fully depressed. Then it would die. After sitting a few minutes it starts normal. Both times I didn't have my obd2 adapter for my torque pro. The last time it happened I went home and hooked it up and got no codes. Everything looked fine. What could it be, where should I start looking. Batteries are1.5 years old. Oil, oil filter, and both fuel filter changed about 1000 miles back. I have had the truck for 1.5 years and the oil has been changed twice. Any help would be greatly appreciated.

Sounds like the FICM is going bad. It is the fuel injector control module. Common problem with them. They get cold solder joints on them. Also some of those 6.0 had issues with fuel injector wire harnesses.I think that was taken care of though by the 2006 model year.

Ditto on the FICM. Just replaced mine last week. Same symptoms you were explaining.
