Hey guys having a small problem with the 8 first then info:

2004 6MT
~98k miles
Recently replaced coils + plugs

Mods:
RB Midpipe
HKS HiPower
Under driven pulleys

So the problem started about 4 days ago. Started hesitationing while doing above 40 mph, on the highway on ramps, but is no longer limited to turns. There is no difference in RPMs or speed just an annoying hesitation randomly through the acceleration process. Even more noticeable while cruising at a constant speed.. The hesitation feels like a sudden choke or lack of fuel.... No misfires just yet, I'm thinking fuel pump but would like to get conformation or other possibilities.

I've read and looked up threads regarding fuel pump failure but the symptoms are similar but not exact... By that I mean I can easily get past 3-4k RPMs and I'm having no issues starting the car..
