I was driving my car at about 65 mph when all of.

I was driving my car at about 65 mph when all of a sudden it stalled and all the dash lights came on. I was able to get it into a parking lot but when I tried to turn it over, it wouldn't start. It will crank but not catch and turn on. I have a quarter tank of gas right now, just had my oil changed, and it hasn't been having problems up until today. Any idea of what is wrong?
