Garry,
Did the engine really "lose all power" or did it just take a lot of accelerator pedal movement to produce in increase in RPMs? The latter is what Gilly referred to as "limp home" mode. Most likely that's what happened. You can still drive the car but throttle response is "weird."

Gilly of course is right that to track this down you need to have the codes pulled. I was the one with the bad brake light switch, but the only way it got diagnosed was via the codes. At the time I had that problem, I was getting an ASR and an ABS light, and going into "limp home" mode every time I started the car. Replacing the brake light switch cured that problem.

On the other hand, I still get an ASR malfunction light from time to time -- about once a year -- and everything works great in between, so if your system is at all like the earlier ones, this may never happen again, it may be a very intermittant problem, or it could be a sign of impending failure of the throttle actuator or some other component. The codes will help decide this.
