Unhappy 01 7.3 Motor keeps shutting down

When I go to start the truck after it has sat for a couple of hours it will start right up and run fine, then after it runs for about 5 minutes or so the truck will just shut down. No symptoms showing it is going to shut down it just turns off. Then I can fire it right back up and it will run extremely rough. Sometimes it works through it other times it just shuts down. Then sometimes if I drive it after it warms up for 10-15 minutes it will just shut down as I am coasting to a light. Other than these problems the truck runs and pulls great it just is a little upset after waking it up. There are also no CEL codes being thrown. Also today when I was going over the motor I noticed a little soot build up near the right turbo inlet boot. Any help is appreciated. I am kind of new to diesels but know my way around a garage.
Thank you in advance for all your help!

I am by no means a pro so don't beat me up to bad here. I would certainly check out the possible leak on the inlet. CPS and ICP Sensors are good ones to check out. Also I had a similar problem with the nut on the end of the IPR sensor backing off. I scratched my head on it for a good while since I could never repeat it, but the truck would sometimes have a hard time starting or just die while driving and then start right back up. Eventually the nut fell completely off at a stop light and my truck was dead in the water. Once I figured out what it was and put it back together it ran like a champ. There is also the wiring harness that sits under the valve covers, worth checking out the connections/wires to see if they are damaged. If they are this will cause injector and or glow plug issues/failure.
Just my 1/2cent. Good luck and let us know if ya figure it out.
