Won't rev past 5,000 RPMS occasionally
I just bought a beautiful 2009 Rx-8 with 65,000 miles on it and occasionally when I'm driving it won't go past 5,000 rpms on occasion, mainly after longer drives. I dont believe this to be a compression issue since it has no problem with warm starts. I'm thinking it may be a clutch issue based on the research I've done but I would like to see if it could be anything else.

It stumbles and doesn't like accelerate once it hits the 5,000 RPM range I haven't really tried pushing it once it starts doing this just incase it causes further problems. Also as a note I forgot to put in the original post is it isn't causing a check engine light to be thrown

Limo mode? Omp failing?

5000 is a weird one. No valves open in that range. The VFAD opens, but even if it didn't, I wouldn't expect it to choke your engine.
How is your catalytic converter? I would expect a code or 3 if it was blocked to the point of preventing you from accelerating, but stranger things have happened.
What about ignition coil age?

My omp didn't throw a code. Unless my reader wouldn't pick it up.

Limp mode is around 3000 rpm though. It's really limp, you're not going anywhere with that. If you're getting up to 5, it's probably not that. Have a look at the cat. If that doesn't lead anywhere, let's get some OBD data on air flow, fuel trim, afr and demanded afr when the issue presents.

check to see if the SSV is either stuck or not working due to lack of vacuum in the solenoid tank. Primaries only is going to be starving for air at 5000 rpm. Especially with a maybe less than ideal compression engine.
A partially clogged cat converter could be another possibility.
