Below is a quote of another person,I am experiencing similar problems except for "total loss of power" which has not happened to me. Also, the studdering problem in first gear is greatly reduced when the "active skid control" is disabled. My Mini Cooper S was purchased in may 2003. "new Mini Cooper S automobile (purchased in June of 2003) experiences a noticeable and significant stumble when engaging first gear and accelerating from a stopped position. The stumble is significant enough to cause a stall condition and results in unreliable throttle response. The problem is worse at higher rpm engagements, in hotter weather, and with the ac engaged. The stumble feels like a momentary loss of power and then shortly thereafter, power is returned to the wheels. The problem occurs on virtually every engagement but is considerably worse on the first engagement after the car has sat for several hours with the engine off. The problem is less severe when turning the car left or right while engaging first gear. This issue renders the throttle response unreliable and can stall the automobile at unexpected times. No crashes have occurred at this time but the potential for a rear-end collision due to a stall or a side impact collision due to stalling when crossing an intersection is present. Additional issues related to engine management and throttle response occur in the same automobile have occurred but these additional problems have been intermittent and difficult to reproduce. In general, the additional problems seem to occur in on temperature days with ac engaged and include a full loss of power for an extended period of time while engaging first gear and a noticeable surging during acceleration as is the driver was pressing and releasing the gas.

" I am experiencing the exact same problem. I would only like to add that a car had to move into the median because my Mini lost power while entering the freeway.
