Any ideas as to what my problem might be with my car? on 2000 BMW 540i

I got into my car to go home from running a quick errand and when i went to start my car it just shut off....no power what so ever!! I tried to jump the car but as soon as i put the jacks on the lights came on in the car but still no actual power to start it up
