May be you are hitting issue related to "Cause: API Proxy not deployed on one or more Message Processors" in below link.

https://docs.apigee.com/api-platform/troubleshoot/runtime/404-unable-identify-proxy-host

if it is replicate at will then may be if you enable debug on MP(where issue occurs) & on the one where issue doesn't occur to compare to identify the issue..and may be open a case with all the diagnostic information and work it out to avoid un-necessary restarts.
