Here in Nova Scotia looking for answers to loss of power problem still.
It just so happens I too had a power loss problem 2 weeks ago (though yours sounds worse).
For me it turned out to be that the sensor on the
SIDE of the airbox (not the MAF sensor) was loose - it has a piece of crap retainer clip that seems to break pretty easy, as soon as I taped that sensor in place with some electrical tape the jeep came back to life and I had full boost again. I also had a CEL with a P1189 code, I didn't realize it right away since I am running the ORM too, so I always have a CEL anyway.
Apparently if that sensor is not seated tight the ECU puts the truck in "limp mode" as a safety precaution.
Anyway, just thought i'd let you know in case it may help you too.
