Truck Starts Normally and Runs Fine. Suddenly Quits. Won't Restart for Hours. on 2002 Ford F-250 Super Duty

Recently ran out fuel. Have since replaced the CPS, the water separator, and changed the oil. Two different times, it has quit in the road. Yesterday, I turned it off and had to have it towed home. This morning, it started perfectly. Any ideas?
