I had the same problem with an 06 Envoy Denali. Engine died in traffic, wouldn't start. towed to York, PA GMC, When they got to it the next morning, started fine. $300 ignition switch replacement. 150 miles down the pike it dies again. towed again to small shop and checked right away, "No power to the fuel pump". underside of engine compartment fuse block corroded. $800 replacement fixed it, now four years ago.
