Well this is a tricky issue to solve....I have seen seldom disconnection...but mostly at startup...not really during printing.
We have observed the type of disconnection you mentioned with RPI model 3. But with RPI model 4 or 5 not really. It seems high load on the RPI triggers this issue.
What is the toolboard temperature? Maybe you have have a high board temperature?

I'm running RatRig V-Core4 500 with a Orbitool board. I keep getting lost communication error. I've tried multiple toolboards, USB pcbs, and cables. I ordered 3 toolboards, so I had 1 for IDEX and a spare.
It seems to work fine for 4 or 5 prints, then I get 3ish hours into a print and it shuts down due to "Lost communication with MCU 'toolboard_t0'" Then it does it every time I try to print something until I switch out the board or cable. Then it will work fine for 4 or 5 prints. I'm really stumped on this. All the connectors are stock, I didn't crimp anything. I've switched out previously removed boards and cables, and it will still print 4 or 5 prints without issue.
T/S info:
RatOS 2.1 Changed stock toolhead cables - I have rotated out 3 different stock cables Changed USB cables - rotated out 3 stock cables, as well as a known good usb 3.1 cable Verified 24v - 24.3v while printing Reported temp while printing: 70-75c The VC4 part cooling fan draws air across board while printing, so there is a constant flow of air across the heatsink.
I can provide the klippy log, but it's too big to attach here.
