If fuse was bad it would not start at all, definitely not the fuse, running for a while usually means that something gets hot, and thermal switch kills it.
Sorry to get your hopes up but I have a similar problem with my 2005 Yukon Denali. How long does the truck stay running before it shuts down? Mine started out with short spurts of the truck shutting down while driving. It slowly progressed to the point where it will only run for about 45 seconds. Originally the truck would sputter the gauges would die and then the truck would die. It slowly progressed to the point where it only runs for 45 seconds and there is no signs before hand. Does any of this happen to your vehicle? I have checked all of my cables and the main ground wires. Along with changing a few of the relays. Nothing has helped. My problem started with an electrical component heating up and quitting. Now it doesn't matter how hot it is in only runs for a couple seconds.
Could be a sensor , but without testing , this would be a guess ! Have seen TPS - throttle position sensors on chysler products do this , Mass air flow sensors on GM vehicles , plus bad IAC - idle air control motor . Don't think you would like to replace all these parts , your best bet , take it to a qualified repair shop . Have it tested !
I have the exact some problem 01 Yukon 5.3 – Sometimes my security light also comes on for no reason? Wonder if this has something to do with the remote starter? When this does happen all I have to do is wait for 15 minutes and it fires up just fine. Pisses me off though…
It sounds as if your alternator may have gone out. If you take the Yukon by an autoparts shop (Checker, Autozone, etc.), they can run a quick charging system test for you. Good luck!
