Low fuel pressure CEL

Low fuel pressure CEL
I have a very occasional low fuel pressure CEL and a short < 2 second loss of power. It seems to happen if I nail the accelerator off the line. The fuel pressure shows as 300 Kpa ( 43.5 PSI ) when I pull it from the computer, but that is after the event. The CEL clears on its own after a couple of cycles.
My thought is either an intermittent problem with the fuel pressure regulator or the fuel pump is on the way out. Any suggestions on what to try first ?

May be worth changing the fuel filter first.
see what happens and move on from there.

Thanks, I have replaced the fuel filter. I used a Mahle filter. Its a 2006 4.2 S-Type with 110,000 miles.
