It sounds like you have an electronic part that is heating up and shutting off the engine. Once it cools enough the engine restarts but for shorter time makes sense as the part will not take as long to reheat. Not sure which part it is but sound electrical to me.

That was a big problem with the old ignition modules.
Yea, I know that. I was just saying your symptom is just like that problem with the modules.

With everything he has replaced, I am not sure there is much left that a "heatsoak" would cause errors with. The one exception would be a vaporlock in the fuel rail, and I cant remember if the 2005 models were return, or returnless fuel systems. I know there was a change right in those model years.
If he had a older truck, than I would suggest fuel injectors since the older trucks run in batch fire.. or the older ignition modules (like previously mentioned). But neither of these are relavant here..
Unless the ECM has a crack in the board, and heat soak is causing it to spread apart.. But even thats a stretch.

I see what you did there...
Crack it or stretch it, probably not good either way.

For a few bucks you can get a tool to test spark at the parts store. It goes inline with spark plug wire.
Most all of these parts have a diagnostic procedure so you dont have to guess if they are working or not.
Do you have a fuel pressure tester? what about your fuel pressure regulator? Maybe it is defective and cutting off fuel somehow?
