I just figured out my problem and it was not the fuel delivery or pumps after all. Turns out an entire bank of coils was firing intermitently and sometimes not at all, and this was giving a lean reading on the wideband, lack of power etc. Last time I had the engine out I didn't put the rubber boot back properly on the connection to this bank of coils and it had moisture in it. Its really surprising how well the engine idles on only 3 cylinders!
Costly error, but I got the beast running again and I have a perfectly good spare pump. I now understand the pressure drop off idle too and will be making a few adjustments to my fuel pressure regulator.
