Can a high CPU spike kill my Azure VM?

Through investigating I realized after a high CPU spike, my VM restarted on its own and since then I am unable to remote to it. Testing the connection on the Azure portal shows I should be able to connect to the VM but I am not able to. Has anyone ever experienced this issue? Any way to resolve it?
I followed the Azure RDP troubleshooting doc and none of those steps worked.

I haven't noticed a restart caused by high CPU load on a VM so far.
The VM restarted in Azure or it's just a restart of the OS of the VM?
Maybe it's worth to redeploy the VM on a new Azure host. You can do this in the Azure portal:

Hi @Anonymous ,
ah ok.
Do you see the restart of the VM in the Azure Portal in the Activity Log?

@Andreas Baumgarten unfortunately no. Tried the redeploy again and still nothing. I also try to troubleshoot and I keep getting this message even though the VM says it is already ina running state:
Hi @Anonymous ,
if there is no reboot in the Activity Log of the VM it looks for me the VM OS maybe crashed/restarted. Are there any logs with helpful information (EventLog if it's a Windows VM).

Yeah I am thinking it crashed but in boot diagnostics it shows the screenshot that it is up so I am a bit lost on what is going on. As for the logs, none to reference at the moment. Even if I try restoring from a backup it doesn't work. Which is expected considering the backup would have been after it crashed. The backup items before restored fine but I would still like to have an idea on what caused this in the event it happens again.
