I'd say pull out the superchip and see if anything changes...

Check all of the grounds on the block, verify wiring around the starter area has not been burned look for pinched wires.

Disconnect the battery and pull the fuse box and make sure all the connections are seated..

So i got this from chevrolet forum.. and it worked super happy
I currently have this problem in my 2008 Silverado.... have owned it less than a week with only 19000 miles on it. The door locks go wild locking and unlocking, guages fluctuate, compass display in mirror flashes illegible digits, strange stuff! I had it at the dealer today and they went through the mega fuse / connections (see TSB below). Everything seemed fine then the ghost returned later this evening. Clock reset and guages dropped momentarily.

Did you get a fix for yours?

Here is the tsb that I found online.

Recommendation/Instructions:

If you experience one or all of the following concerns and a cause for the concern can't be identified, please check the following items:
1) Remove the 175 amp Mega fuse and inspect for arcing, if any type of arcing is found replace the effected components.
2) When re-installing the 175 amp Mega fuse, torque fasteners that attach the mega fuse to the positive cables to specification in SI.
3) Check the voltage drop reading on the positive and negative battery cables. The voltage drop should be performed with the fuel injectors disabled and while cranking the engine. The voltage drop should not exceed 200 mV. If the voltage drop is above 200 mV, replaced the effected cable.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
