2002 GMC Envoy engine shuts off while driving?

From what I've found with my 2002 envoy, apparently there are issues with the fuse panel under the hood. If you remove the 2 covers on the fuse panel, you will see 3 bolts that hold the fuse box to the frame. These bolts also serve as a ground for that panel. Make sure they are all tight and even try loosening them and re-tightening them to make sure they are making good contact with the frame. I had one occasion where my envoy died in a driveway because I checked the fuses for issues and it caused that panel to loose ground. The other issue came about 2 weeks ago while I was on my way home on a 4 hour trip. It cut out unexpectantly while I was driving. I asked my dealership if this was a common problem and he said yes.
