It sounds like the OMP is going( Oil metering Pump).It will put the engine into limp mode and you get a real big lack of power so you know that something needs to be attended to.
You can pull codes on your engine as it is an S5.
Try this:
RX7 FD and Series 5 Error Codes

having the same issue sounds like the omp but also check the ecu because a bad omp could damage the ecu as well
