Sudden power loss & dash reset while driving

So, something kinda weird happened yesterday while I was driving my Acadia on the highway. Out of nowhere, I lost all electrical power,like, the dashboard went completely dark, the radio shut off, and the gauges reset as if I had disconnected the battery or something. It was super unsettling for a few seconds, but then everything just popped back on, and the engine kept running like nothing happened. Everything just came like nothing happened. Has anyone else experienced this?

That's a terrifying experience on the highway, glad you're safe!
This sounds exactly like an intermittent main power connection issue.
Check your battery terminals first, make sure they're super clean and tight, both at the battery posts and where the cables connect to the frame/engine (grounds) and the fuse box.
A loose or corroded connection can momentarily break contact

Not at all to me, thats scary as heck. Glad youre okay though. Yeah, i'd check your battery terminals and wiring to make sure everything's tight and corrosion-free. Its all you should focus on right now
