While driving on the highway, my 2003 GMC Sierra 2500 displayed a "reduced engine power" warning on my dashboard. My vehicle lost all speed control, decelerating from 65 mph to 20 mph in a matter of seconds. I immediately pulled over to the side of the highway and shut my truck off. Once I restarted the vehicle, the message was gone and my truck was fine. It was a very scary incident not being able keep the right speed for the conditions on the highway.
