2003 Hyundai Accent

I have had my car for 5 years and have never had an ounce of problem with it. Last night I started it up, no hesitation, no problems, drove 2 miles and at a stop light, it just quietly died. It didn't sputter or buck, just stopped running. All the trouble lights lit on the dash. When I tried to restart it would strongly crank, but would not turn take and start.
gas tank 1/2 full, all lights working.
What do you think it could be?
