I was coming down my hill, and my engine just died. it's happned once before. my stereo was on, and it didnt cut out when my eninge had died, so I don't think it was an electrical thing....any ideas?

i was driving one day and my car just died on me too, woudlent start or anything, turns out there was a short by the o2 sensor and it blew a fuse, i was back on the road in no time, but i did have to get it towed to find all this out

 

Does it only cut out coming down this hill or is it purely random when it happens?
