OLD NEWS:
So after my last trip to Moab, I was driving over Vail pass to come home and the SUT bogged down and killed over and over. Push on the gas it was worse. Pulled the battery cables and re-tried and problem solved. Dealer said it was some kind of O2 sensor issues. Also had some fuel canister changed out. No more issue since than and dealer could never duplicate. OnStar did fn\ind issues when diognostic ceck was done.
NEW NEWS:
So I went to run McCalisters Gulch today. So I packed up the wife and dogs and off we went. YIPPEEEE!
Get to the trail head and start to make my way up some steep sections and having a blast. Get up to the Summit (1/3 way into the trail) and have lunch... just before is starts to rain.
So we continue on to see this new trail that we have NEVER been on before. Just geting to the highest elevation and the truck starts sputtering. ****!!! DAMN!!!! F&%$! Truck dies. Re-start and it does this for a couple more times. Than up and over the top of the summitt and start my decent down the other side. HMMMMM. No more sputtering. Odd? Stopped raining too. OK, not too bad, can't turn around even if I wanted to. SO we keep on goiong until it starts raining like a beotch.... and we found out we missed our turn. DAMN IT! So I go to turn the truck around. Keep in mind at this point I'm somewhere between Bumblefu&* and you got a pretty mouth. the SOB dies again and does this about 9 times. So I get turned around and head back and run into this really nice guy running a D90. LOVE thse rigs BTW. He showed us the way out and made sure we made it back to Denver. Thanks dude!
So now my SUT is in the driveway (all washed up already) but scratched to piss. (Kind of looks like Adam's truck now. JK).

Now I have to drive this thing back down to the dealer again. So pissed at this point. OnStar said their are no issues coming up on their diognostics either. So I'm guessing the dealer won't figure this out either.

Thoughts? Other than me going on and on?
