Mk2s: Error Thermal Runaway but can it be?
Had this runaway error but it was weird cuz it would print 5 layers (15 mins per laye) and fail in the same height the few times i tried. The weird thing is it wasn't a high temp issue it was showing ten degrees lower than the target for almost the whole print. I changed the heater and thermistor flashed updated FW and PID tuned and everything looks ok. Any thoughts?

Have you checked to see if your connector is melted where the heat bed connects to the main board? That's what mine did when I got that error, and is a common error and design flaw of the Rambo mini board. I had to solder the wires directly to the board, fixed.

Yeah, believe it or not it was two bad thermistors. The one in the machine then the new one I bought. I used a multi meter and realized the new one was defective as well. Thanks for the help!
