^A very good chance. There's something inherently wrong with the fuel or ignition system on the N63 and probably the S63 as well.
Your speed dropping that much is weird, though. After it misfires and triggers the fault, it should only go into limp mode - it'll stumble and bog when trying to accelerate, but it shouldn't slam on the brakes for you. In the future, put the tranny in "S" mode when this happens - keeping the RPM's up by having the car gear down for you will help it chug along.
