car wont go past 2k

So the day i got my rx7 i drove way down south to trade my car for it and on the way back i stopped at stancewars seattle to check it out but when i went to leave my car wouldnt go past 2k rpm and when i tried it would bog down and shakenreally hard. This lasted for the time it took me to leave the college campus it was held on so about 5 mins then it started to work perfect. Anybody have any ideas?

Pull the fuel pump sending unit, inspect tank/pre pump filter for heavy debris. This assumes motor's healthy & making compression, which you can get a rough feel for by pulling the lower 2 plugs & cranking, AFTER pulling both EGI COMP & EGI INJ fuses, and listening for 6 even pulses during cranking. Should give you a place to start, anyway

Ive done a compression test and it holds great even compression on all seals. I really dont think its a fuel issue. It maybe happened for 5 minutes then stopped and hasnt happened since. Do these engine have knock sensors? Any sensor failures that would put it in any kind of limp mode?

S4 cars don't have knock sensors or a limp mode, but S5 cars do.
