HEATBED THERMAL RUNAWAY but I just installed a new OEM Thermistor. Suggestions..

Well that didnt fix it.

I preheat for PETG, and watch the temps. Nothing is moving (bed or hotend) and I'm watching the bed temps very slowly drop starting at 85* and over about 5-10 minutes it dropped to the high 50's. I tried moving the print head around and the bed and it's still just slowly dropping so I don't think it's wires.

It just hit 54* and errored out again.

Any clue? Is it the bed or the Einsy RAMBo board or what?

The one that connects the power to the heatbed. Locknut and all it was loose. Never seen that on any of my printers.
