Gauges lose power, CEL flashes, car drops a gear, Happened twice now. Options

[xs94st]

As the topic says, I'm driving around 70-75 on the 15 and I lose gauges n it will go on n off until I'm around 40. First time it happened it continued until I pulled over n checked the engine. I disconnected n reconnected the battery n drove fine home. It happened again today when I was going to pick a part.

Speedo loses power, heater gauge, tach lose power on and off. Sounds like it drops out of overdrive as well. Any suggestions? I checked grounds and very thing seemed fine. Thanks all.

Is it just the display losing power or is the entire car shutting down?

My bad, typing on my phone with grease all over my fingers. I'm surprised I didn't abbreviate everything.

95st - it was just the display. My seatbelt light stayed on constantly (have to replace airbags)

The only ground wire that I see that could possibly e of issue is the large one that is slightly frayed.

I'll take it all out n get a good look of things once it's not 90 out.

By the way, anyone out in the Inland Empire, there were two sixth gens there. One teal, the other bronze/brown? GT and ST models, no front bumper covers but the the rears look fine. I'll post more details in the FS section.
