Check handles count for lsass.exe. If it is above 50K then you will see issue. Also see, which process is actually showing high CPU, when this issue occurs again.

Is this VM or Physical? And how many CPU and RAM assigned to this server.

I see you have very low hardware, 4 GB with 1 CPU pretty low. You should minimum get 12-16 GB RAM with minimum 4 -8 cores.
