This happened to me once about a year ago. I was coming to a stop in traffic (from probably 35-40 mph), and after I stopped, the car died. The radio was still playing, headlights were still on, it's just that the engine died silently, and I didn't feel it jerk or anything.
I thought it might have been my battery because I was having a corrosion problem at the time.
