05 6.0 rough idle

In need of some help. I have an 05 6.0 that ran fine this morning for work. Went to go get some dinner and I noticed after coming to a stop that my truck was idling rough. Luckily I was able to limp it home. When I go above 45-50 mph, the truck starts shaking with next to nothing in power and with no codes on the dash. When I parked it I pulled the oil cap and held a piece of paper up to it and it wasn’t blowing the paper or was smoke coming out. Shut the truck off and listened to the injector self test and it seemed shorter than normal. I then pulled the starter cable and touched the pos terminal on the battery and the cranking seemed fine. So I’m hoping it’s not a “base engine” problem and hoping someone can shed some light. There is also no smoke coming out of the tail pipe. Any help is appreciated!

Likely a fuel issue

Have you changed the filters "lately" ?
Fuel pump sound strong at key on?
More than half tank of fuel?
Would be good to do a fuel pressure test -- need a gauge for this

In my defense, I was unsupervised

General note:
For all those wanting a premium silicone sealer Kubota 70000-73764 is the best your gonna find. This is a hybrid gray silicone that uses solvent rather than acid to start the curing reaction, this makes it safe for aluminum and and any surface that involves coolant.

I have gauges when the truck was BP a few years ago. After I calmed down and slept on it looked at it again. Cycled the key to listen to the pump/injectors sounded weaker than normal and I kind of noticed it when I replaced both filters 2 weeks ago but wasn’t sure And the pressure goes to around 78 psi on my gauges. When it was running it dipped down to about 55-60(guess I need to be more observant). I said last night I didn’t see any white smoke out the tail pipe but I was expecting it to be like the video “6.0 bros” posted but it wasn’t as bad and with it being daylight it’s easier to see. So I’m going to replace my fuel pump with the stock motocraft pump and I’m looking at the alliant ap60901 injectors and updated dummy plugs but was wondering if anyone has any better recommendations on injectors. This truck currently has 188k on the clock.
