Today while driving over a speed bump, my car.

Today while driving over a speed bump, my car died. It was running fine, no spuddering or anything to make me think it was dying, or running out of gas. However, I was low on gas so I tried to see if maybe I had run out. No luck. Can you think of something that maybe happened, like if I could have knocked something loose by going over this bump? I was going slow. Just trying to narrow things down that I might need to check out. When I try to start it, it makes the noise like it is turning over but does not even try to run.
