Did you put your vCenter on shared datastore and enabled HA on the cluster ?

Very strange behavior, anyway can you check if the VM of VCSA are HA Protected on the Summary tab of the VM and if the HA failover is not disabled for the VCSA on the cluster HA configuration ?

Check the following:

- Right Click Cluster

- Edit Settings

- Virtual Machine Options

- Virtual Machine Settings > VM Restart Priority

Make sure the vCenter VM Restart Priority is not Disabled... and I will recommend you change to High, cause if there is not many resources available on the host2, maybe the vCenter fail to restart due the insufficient resources on that host.
