2005 WK electrical issue

Hey guys. Electrical issues are my least favorite so I petition the brain trust.

Driving back from work today my dash lights (everything) and cabin fan would flicker off very briefly, then come back on. When everything came back on it was as if the key had just been inserted and turned.

Headlights did not flicker off and no noticeable engine power changes during flickers.

This happened several times. Finally, the 'SERVICE ELEC BRAKE SYSTEM' messaged showed with the warning light staying lit as well. Lights continued to flicker on and off until I got home.

Any ideas? I slammed on the brakes on some snow/ice and ABS did NOT kick on so that would be the obvious place to start, but want to make sure there isn't something simpler that might be the cause.

Thanks!

EDIT: I wonder if this is related to the safety recall I received recently...let me dig it up.

That code is for: Lost communication with Final Drive Control Module
