Bring up the printer console while printing, and check for error messages when it stops. It'll give you a clue what is going wrong. For example, if either the bed heater or the bed temperature sensor fail (I replaced both of them, the later one even twice), you'll get a temperature alert. Temperature slowly drops -> bed header. Temperature suddenly becomes 0 -> bed temperature sensor.

No error messages. Switched to windows where I could disable the USB power saving mode. Seem to have solved the problem, testing all week by setting up large prints before I go to work.

Any way to do the same on the Mac side?

Update on this issue for me. I've been setting up 10 to 12 hour prints each morning before I head to work all week. Every one has finished without a problem running my iMac on the windows side. This leads me to believe the problem is in the USB ports power saving modes, which I have disabled in Windows but do not know how to disable in MacOS.

The Macos directions for Cura LulzBot Edition have directions for disabling the sleep settings for Mac: https://www.lulzbot.com/learn/tutorials ... tion-macos

We hope this gets you sorted!

That doesn't fix the problem however. The issues is there is a low level power saving mode built into the mac's USB hardware. In Window you can disable this power saving mode in Device Manager, but I can't find a way to do this in MacOS. I'm find running on the windows side.
