VMs Fail Randomly on 2012 Cluster

Our 2-node Server 2012 Hyper-V cluster is having an issue where VMs seem to randomly fail for no apparent reason.  We are using Dell R900s with a MD3200i SAN and we have separate networks for iSCSI and Heartbeat.  On one of the nodes we get an error 1069 "Cluster Resource 'Virtual Machine VM200X32' of type 'Virtual Machine' in clustered role 'VM200X32' failed."  Below I have listed the relevant cluster log events from around the time it fails.  The cluster has passed validation and is running 50+ test VMs just fine, it's only a few of them that seem to be having this issue.

Just wondering if anyone else might have some input on what the problem could be.
