Lost communication with MCU 'toolboard_t0'

Hi, I am at a loss with my Vcore 4 400, it has been plagued with Lost communication errors. It worked great for the first month and then I would get Timeout with Lost communication with MCU 'toolboard_t0' errors a few hours into prints. I replaced the USB-C cable recrimped the power to the toolboard and then the printer worked great for another month or so and now I am getting the same issue again...

Is the USB cable well attached at both ends, zip-tied to the printhead? Quality multi-strand cable so it doesn't die so fast?
