Zoom Meeting Disconnects In 10 Minutes at Weekly Scheduled Meeting, Why?

The only time I've seen this issue regularly occurring like this is when more than one person has access to the account (account sharing -- intentionally or otherwise) and the other user starts a different meeting, causing the current meeting to be terminated.  Perhaps change the password for the account, and see if that helps.  If not, please post some additional information and I'll see if I can help figure out your particular situation.
