Ignition Switch Problems of Chevrolet C2500

Vehicle stopped running at 65 mph. Dashboard lights did not come on. On the side of the road (where I was able to pull off the highway) it finally re-started. I brought the vehicle home. When I attempted to make another trip, the same thing happened. I was less than a mile from my home. I eventually was able to restart. The final outcome was that the ignition switch was the problem. I called the dealership and they advised me that my vehicle was not part of the recall. I believe that it should be included in the recall for gm vehicles. My truck is a 6. 5 liter diesel. Which may be the reason it was not included in the recall. I believe this is a factory defect and should be included in the recall.
