Question about 2005 Ford F 350 Super Duty
Change the plugs, wires, distributor cap and rotor - air filter and fuel filter. Also, once it's started and at operating temp - pull the vacuum line off the distributor (if equipped) and put a timing light on it. If it needs timed, do so with the vacuum line off - once it's set to where it should be, re-connect the vacuum line and adjust idle as needed.
After this, fill up the tank, (one of if two) and poor 3/4 can of SeaFoam in the tank. Pull any and all vacuum lines and insert them into the can - (hold idle up with hand or have someone help to prevent truck from dying). Run through the entire tank, and refill with desired grade fuel you usually use.
Also, make sure you have no exhaust leaks at the manifold, intake, catalytic converter, or muffler.
The catalytic converter may need to be checked as well, as if it's plugged it will suppress the engine exhaust.
Please let me know if you need any further assistance.

You may have low fuel pressure which the engine isnt dealing with while cold. The engine uses base setting during warm up and then switches to active sensors once warmup is achieved.
You should also make sure you have spark at all cylinders. Sometimes a plug gets chewed up by detonation and ends up being way out of time!
How many miles on the engine?
