You getting any codes from the ECU? I'm having the same issue and I've narrowed it down to the knock sensor.

Haven't gotten to it yet, so I'm not 100% sure, but both our cases seem like a knock sensor issue. Breaking up bad when revving. Although for me it only happens under load. Check if your ECU is throwing code 34.

Oh and if your fuel pump stopped priming, it might be an electrical issue. I had the ground on my alternator go bad, which made everything go whack.
