I've got a Trailblazer with the 6.2 inline six. I haven't had this problem but hoping it's only on the v8's.

FYI: (For those reading this for first time)
Not sure it would have helped you find the problem on this site but mentioning all of the symptoms you were having would have pointed to some sort of electrical problem. I had a similar issue some time ago on my 68 and it turned out to be a defective low/high beam foot switch. Nothing scarier than going 65 mph at might on a dark country road and losing all lights.
