My gl 320 ? 2007 lost all electrical power and the engine stalled while being driven. The power comes back on in 10 to 20 seconds and the car can be restarted. This happened 3 times during the first 10 days of oct 2009 when the mileage was just under 30,000. Note the power steering and brake assist go out completely as do the headlights. On one accession at night on a curve I went off the road before being able to stop. On all occasions this happened 15 to 20 seconds after applying the brakes to deactivate the speed control and after coasting to less than appx. 40mph. The dealer could find no direct code indication for the problem but did find numerous low voltage codes and changed out a number of fuse and refuse boxes and fuses. The car has been driven only 100 miles since the dealer work and the problem has nor recurred.
