My 07 Yukon Denali dies and won't restart until it cools down.

I had a similar problem with my 2002 XL Denali. It would shut down for no apparent reason. Then it would restart and run okay after about 10 minutes. After a few episodes over a year, I finally took it to the dealer. It was the fuel pump inside the gas tank. It was overheating and it would shut off automatically. After it cooled down, it would work okay. Cost me $900.00 to fix (after I was stranded on the Interstate during a vacation trip.)

Just replaced the fuel pump in my 07 last week. Had the same problem this morning with a full tank of gas. Also noticed my gauges don't work properly when it is going to have this issue. After 3 hours sitting it started and ran like a champ. I have only had this issue while pulling my snowmobiles or a trailer.

Can you tell me if you ever resolved this issue? My 2007 Denali is doing the same thing. My issue is I just had the fuel pump replaced. I didn't have the issue before that. Thank you!
