While traveling on I-49 North at 50 mph in Kansas City Missouri, our Land Rover lost electrical control of car. The car shut down the engine, power steering and power brakes leaving the car drifting without power at 50 mph on the highway. The driver was able to coast the car off of the highway without injury or collision with another vehicle. The car had lights and radio power but could not be started. Once stopped the car's emergency brake could not be engaged, so the driver had to stay with the car to keep it from rolling. The car was towed to the dealer after the event. Five seconds prior to the power shutdown, an indicator light came on that said restricted performance. Other information is: 'earlier that day the car had been refueled with premium gasoline 'the car has a one year old battery 'the car has had problems since purchase with the keyless entry. Some of the key I have will roll down the windows instead of lock the car doors.
