As I was leaving las vegas on I 15, I got a message of reduced power. I was just out of heavy traffic, traveling about 70 mph, when the engine slowed to about 1,000 RPM with out warning. Found out later that it was a broken lead wire to the throttle position sensor. The truck had about 37,000 miles onit. The truck is a 2007 2500hd with 6.0 engine. The trucki has never been worked on, and is line new. Dealer installed P/N 88986255 connector. I received half or the cost back after calling GMC. I feel that this is a safety problem. As I was just out of heavy traffic and could pull off of the road.
