Did they scan for codes?
Sounds like a fuel issue, but I'm searching here. So I would check the fuel filters and see if they need to be replaced. If they are fine come back and let us know.

I’m guessing it’s a 7.3 losing power while driving could be oil solenoid at the time of the fuel pump oil psi sensor cam/crank sensors pull the connectors check if oil is inside either end of the connections if it happens when engine is hot than that’s a good indicator you have a cracked sensor
