My Boxster spends the majority of its life on the racetrack where literally every shift is made at redline (around 500 upshifts per race weekend) and I can assure you that there is no flat or dead spot at 6000 rpm (and I am on my 4th engine so I can say that this is true for more then just my current engine).
I agree with your logic regarding the fuel pump and coils. My only other thought is to check the throttle cable just to be sure that its smooth and linear and not hanging up momentarily somehow (a bit of a long shot but I'm running out of ideas!).
