I am actually having the exact same stall problem with my 2000 Tahoe Z-71 as I write. Over the holidays I was travelling and it happened twice. Basically the engine would start and I would get moving and the Tahoe would stall. After stopping and getting back in park, the engine would restart no problem and then I was able to drive. This actually occurred twice on successive nights. I happened to have a buddy working at the local Chevy Dealership in the service dept, so I took it in and we looked through everything. No codes from the computer and the only potential electrical problem we could find was a slightly loose ground wire leading from the battery to the block. We tightened this and everything seemed to be fine. The main reason we believed the problem to be electrical was because upon stalling the vehicle, the clock was reset to 1:00. Thus, there had to be a complete loss of power from the electrical source. Well everything was fine and we got back to home and my wife was driving the Tahoe. Tuesday she went to start it and had the exact problem. So I took it into the local dealership here and then had it overnight and all of yesterday. Finally they called back saying they could not get the problem to duplicate and thus couldn't find any problem. I drove the Tahoe today and it happened just the same. My question is: why would there be a reset function to the clock? When this happened to me today, there was two sorts of stalls, one that reset the clock and another "less-invasive" that did not? I'm pretty much at a loss and I think it may be fuel related, but again why the clock resetting? If anybody has any suggestions, please help out.
Thanks
