Please attach the output of hosted-engine --vm-status and the
/var/log/ovirt-hosted-engine-ha/agent.log file from both hosts.
The VM will restart if the ovirt-engine service does not become
available within timeout. And that might mean couple of things - the
FQDN of the engine is wrong, the engine needs something that was only
available on the dead host (A) like some storage, host B cannot ping
the gateway..
Best regards
