F series self reboot after 5 hours of CPU-intensive simulation on Maya Bifrost

Doing some intensive simulation on Autodesk Maya Bifrost, requiring about 50 min per frame on a F48_v2 VM, so that is forecasted to require 40 hours to complete.
I tried twice to complete the sim, and in both cases I discovered the VM was rebooted without my command. On my office PC I can run 8+ hours sim without problems.
The diagnostics say "A reboot was triggered from inside the virtual machine". Running the Troubleshooting tool told me "We identified that a live migration was performed on the VM [VMName] by Azure".
Wanted to ask if this generic message need to be considered valid for my specific instance, and in this case if I need to migrate to a G, M, N, and H series to avoid live migration.

    The sim is running fine since 25 hours so I think definitelly suspending the Windows update was the solution.
    Hope it make trough it's forecasted 60 hours (changing a few parameters increased to 1h33 the time per frame) before completion without any more problems.
