Sounds loudly like - first, ignition coil/coils (the Bremi brand coils thy came stock from the factory are now being replaced when they wear out with BOSCH coils at the dealerships - FYI). If you do have a bad coil situation, much better to have all of them changed while the work is being done. Second possibility is the MAF which may have caused your car to go into "sluggish/sleep mode". Having said this, I just had this happen on my E46 M3 which, while air flow on mine is very different, the root issue is the same. I'd all but bet you have a bad coil. Let us know. Good luck!!!
