@BrettGoodrich I wish I had better advice for you based on the information you provided but it sounds like you might still be dealing with some underlying server configuration issues, perhaps something that you don’t even have control over since it’s shared hosting.
When I encounter problems like this I like to try a fresh install of WordPress just to test the server out before I start debugging my own code. If you can put a fresh WP multi-site install on that server and get a sub-site online that will give you a clean testing area.
If you still see the issue on a clean install it’s most likely a server issue. If the issue goes away the next thing I’d try is an IMPORT to pull all of your site content into the clean install.
You might also consider reaching out to tech support at your host. I hope this information is helpful.
