Truck won't start

[spike]

I have a 01' F250 crew cab power stroke with 38,000mi. I shut it down yesterday and came back to start it about five minutes later and nothing happenes. The lights come on all accessories work but it wont start. I changed the battery,starter,checked the fuses,and still nothin.I waited til this morning to mess with it again, go outside and it cranks right up. I turned it off and tried it again and got nothing. What the F is wrong with my truck? It's to new to have any problems. It just happens to go out when my warranty expires. Any help would be greatly appreciated.
