2002 Chevy Suburban engine shuts off while driving

While traveling at highway speeds for a prolonged time, the engine would just shut down. Just as if someone turned the key off. I would put the vehicle in Netural and coast to about 30 mph and attempt to re-start. After several attempts, vehicle would start and would accelrate back to a average speed of 70 mph. This would occur frequently. Maybe 10 times in a 8 hour trip. The only indicator I would receive from the message center was a bright RED light, all gages would go to off or zero with the exception of the speedometor.

Sounds like a vapor lock stopping the flow of fuel, a stuck water thermostat overheating the engine, or a faulty or failing electrical relay. Take it in for service before you get stuck on the road. Good Luck
