The problem sounds like vapor lock, but vapor lock is almost unheard of with fuel injection systems sooo.
Have you ever had the codes read after this happens to see if its leaving a clue?
If I was gonna troubleshoot this I'd do the following next time it happens:
Retrieve any stored codes, maybe its a sensor getting a faulty reading and shutting the truck down to prevent damage.
Check fuel pressure, see if the fuel line has liquid or vapor in it.
The next step depends on your findings.
