Electrical Problems -major Loss Intermintently

I have read all of the posts relative to this issue, but am still seeking guidance.

Tonight, all dash gauges remained lit but dropped to '0' for a few seconds, all dash warning lights flash, and engine dies for a second. Mirror compass alternates between all LCDs lit and actual compass info. Driver info center resets showing 'Driver 1'. Engine stumbles, but continues to run. All lights stayed lit and no external lights seemed to be affected. This happened 25 times in 8 miles. An experience to be sure. This 2004 Avalanche had the underhood fuse block replaced under warranty. Currently has 60,000 miles showing on odometer. Battery is less than a year old.

I have checked nothing as yet..Trying to get a head start for research and repairs. i will check battery cables first, then proceed from there.

Any other ideas or the typical ignition switch problem? Thanks for reading and hopefully offering solutions.
