Guys, i really need your help to find out whats wrong with my 2006. On a regular basis, when i first start my truck, everything is fine, but after about a minute or so, I lose power to the radio and every guage in the instrument cluster will zero out. I look at the odometer and "TEST" is displayed. If i push the button to reset it, it says "SWEEP GUAGES" and then all the guages appear to go nuts and finally settle back to where they are supposed to be. If I continue to press the reset button (trip) it takes me to all different sorts of data. Can anyone tell me what is causing this?

Somehow you are entering dtc test mode....my guess is the battery is weak....clean your battery posts and have the battery load tested, these new vehicles are set up to run things based upon voltage sensed, and even the slightest variation will cause things to work improperly.
