If the fuel pump(s) run while the pressure is falling, replace the fuel pressure regulator and (although I'm sure you've already done this), replace the fuel filter. If the fuel pumps appear to be turning off by themselves, replace the inertia (fuel cutoff) switch.

Have you changed the plugs, if any are fouled out or if any are worn, it takes more to fire it under load and may be spark knocking because one of the plugs can't fire off all the gas and cause it to skip or idle rough.
