I am having an intermittent problem with my 2003 H2 Hummer. Specifically, I can drive it for miles, then when I exit the vehicle and return to the vehicle, it won't start. This might occur once a month. It might occur once every other month, etc. I have taken it to the Hummer dealership and once they jump start the vehicle, it cranks and runs fine. Does anyone have any suggestions?
