Check Engine Light On problems of the 2009 BMW 528

I was driving the vehicle on the highway about 70 miles per hour - when without any warning the vehicle "check engine light" and "hazard lights came on - the fuel gauge showed over 100 more galloons in the tank than it had previously - tried to accelerate but the car did not respond. The engine reduced power and was stalling as I immediately started to cross the highway from the furthest left lane in order to get to safety on the right side of the road - I was with my parents and my handicapped nephew and scared for all of our lives. The engine "sputtered and vibrated" before stopping. I didn't notice anything wrong or any change in the way the car drove. This was a very dangerous and unsafe incident.
