You checked the fuel pressure & volume, did you do so while problem was current?
Delco pumps are unforgiving when run dry.
If not along those lines, the thing that I would look into is you say it is decreasing P/W?
What is the MAF doing when this occurs?

I tried to send you a personal message but you have that feature turend off. Is your fuel return valve functioning correctly. Mine took a crapper and had hard time starting and it iddled like a turd when you did get it started. Aint no Guru but it's something you can check into.

definately recheck your fuel pressure. so what were your O2 readings at the time this happened? did bank 2 go rich or lean? (high or low mv) are you loosing spark? loose ground?
