Nissan Frontier 2004 engine died while driving on interstate at 65 MPH

My Nissan 2004 Frontier crew cab truck engine died while I was driving on interstate at 65MPH around 10PM at night. All the indicators lighted up like a Christmas tree. I let the truck roll till the exit ramp came and pulled over. It was 25 degrees outside and waited for 45 minutes for the tow truck to come and had it towed to a hotel parking lot. The engine would crank but will not start.
What can cause sudden death of an engine that was running fine all day ? The check engine light came on at the same time the engine stalled.
