If you look in the owner's manual it will explain this. Happened to me a bunch of times, really embarassing. It is an additional anti-theft device . If the computer senses that the key is inserted improperly, or that it is not a perfect match for the code it has in its memory for your key, it shuts of the gas supply to your engine for approx. 10 minutes to defer theft. Still happens to me intermittently. Now only very rarely. Total pain. I cleaned my key..carefully, with WD40 and after drying put just a touch of graphite on the key and started the beast a number of times. My dealer didn't read the manual either. You must wait the full ten minutes before trying to restart....otherwise it never totally resets and (the first time this happened to me) you can sit there and fight it forever.
I don't have my owner'smanual handy to refer you directly to the proper pages, but its in there under theft deterent. Hope this helps......and that Hummer can provide aneasy fix for this.

I brought my 2006 H3 in to the dealer for the same thing. My blower stopped working all together but it started as an intermittent problem. He said he had to replaced a diode or resistor either behind the switch on the dash that controls the fan or on the fan motor itself. Have not had a problem since but that was only about 4 months ago.

To reset your maintenance reminder system (even if the light hasn’t come on yet), you’ll need to turn your key to on (but don’t start!) and make sure your odometer is on TRIP A. Then key off. Press and hold the Odometer/Trip button. While holding down on the button, key the ignition to on (Don’t start the engine!) The display panel will count down from “------“ to “-“Continue pressing the button until the Trip A is displayed. After this step, you are done.

Testimonial: "thanks for the advice that was awesome"
Probably too late now, I am sure you have already fixed it, but mine did this and it was an electrical part that is mounted right beside the blower fan. The part was OK, but the plug into the part was arcing and burned out the connection. A Chevy mechanic told me this has been happening to MANY Chevy products. I had to buy a new part and plug assembly with new wires, about 100 dollars, and I spliced them together. It was an Easy fix, but I shouldn't have had to do it :(
