Question Not much power

Ok the truck has been running great. But it has been acting up some times. When i get on the gas it will sometimes cut out it wont die it just sputters a little bit and then runs fine. Also at 65-70 with cruise control on the truck acts like the tranny is slipping. I have changed the map sensor, the cam sensor, oil, fuel filter, air filter and no change at all. I am lost

Just going to throw something out there maybe it's the TPS ? Does it happen at the same throttle pedal postition each time it does it. You might want to take the dvm to your tps. Sorry I don't have specs off hand.

Is the check engine light on?

Are you able to do any data retrevial from the PCM?

Things we would like to know are:

Fuel Level
Fuel pressure
ICP pressure
Oil level (you said uoubjuat changed but let's check)

There are other possibilities but we will start there I think.

The fuel is never below a 1/4 tank
The oil level is perfect
The other 2 I can't check I have a Bluetooth obd2 adaptor but no program is there one I can download on my iPhone or computer

I believe DashCommand works on iOS devices. For fuel pressure, you need a mechanical gauge. There's no fuel pressure sensor on a 7.3 PSD.

You could pull the ICP plug and see if it stops cutting out. Quick and free.
