I been having an intermiting problem with my 07 Suburban where the instrument panel will go completely out then it will come back on like when you start the car.

Sometimes it may just be the red airbag light comes on then goes out.

Sometimes the StabiliTrak Indicator light will come on then go off, uncommanded, and the switch will not work.

Sometimes the Park assist switch will not allow me to turn it on it's in a locked off mode sorta speak. when I press the switch it just blinks and goes back to being illuminated on the switch (lower center console)
And Finally the other day I went to stow the side mirrors and the car froze up. when I hit the switch they didn't move then I tryed to start the car and all dead except the headlights worked and the only power inside was the light on the heater control panel. After some time she started then stalled dead again, etc. Finally started and when I was driving the intrument panel went all blank then restarted etc.

Any idea?
