Your 03 F-350 has a 6.0L in it and a very common problem is the no start after warm up. This is because it can not build the required icp pressure. It is an injector problem if my memory is right. I believe something comes apart on the injector . It has just been a while or I would be able to tell you the axact thing that it is. I am sure that it is on an injector though.. A scanner would show that it wont build icp pressure while cranking after the engine is warm. Just another 6.0L problem.....

Nope.
Could be, definitely a leak on the high pressure oil system. O-ring can cause this.
Yes, what this guy said. A high pressure oil leak is usually the culprit.
Not going to be even close to the same answer, two way different engine designs.
It COULD be an o-ring on an injector, but in this case I would bet 99% against that. Nothing on the injector itself actually comes apart. I am SURE it's NOT an injector.
Your answer is most likely high pressure oil leak. The engine is cold, oil is thick, it starts and runs fine, as engine warms up, oil thins out and under pressure leaks out and wont allow you to build the pressure you need to fire the injectors. This is a fairly common issue on a HEUI motor.

Yeah, Mine just started doing the same thing this weekend>
. Won't start after the truck is warm. So is this something I should just take to the dealer for the extended warranty($100 deductable) I have or Is it something that isn't to bad to fix under $100. Cause right now can't even drive it to work.
