Alert description: The Cluster service is shutting down because quorum was lost. This could be due to the loss of network connectivity between some or all nodes in the cluster, or a failover of the witness disk.
Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.

Open fail-over snap-in and share the event id's you are getting in the cluster logs.

I have seen this showing up on the Virtual Environment mostly, this could probably be showing up due to some backend network disruption, while some activity performed.

check with the VM team if its the VM setup or with the network team for any activity happened at the time for the specified network in the logs.

if this is so frequent then probably check for the network cards for any issues or firmware/driver upgrade.
