As others have seen, it happens on both clean installation of Windows 10, as well as old installations that are known to work.
Resets are always triggered by an ACPI reset that seem to caused by the guest becoming unresponsive for 4 seconds.
Also worth noting that I bumped the heartbeat timeout to a full minute with the following command:
