Zoom not responding and dropping meeting

About 10 minutes into every Zoom meeting lately my screen freezes, goes gray, and says that Zoom is not responding.  Clients can hear me, but after 5 minutes of that Zoom drops me off the call and automatically puts me back in the call.  Nothing happens to the client except that they are talking and I miss part of the conversation.  This normally wouldn't be a problem except that I am a coach and it's critical to my business that I listen carefully to the entire conversation, not just pieces of it.  How can I stop this from happening?
