I have finally had sometime to look at this again. Pagespeed errors continue to occur. The current instance has roughly 2.3 gb of FREE mem available 4GB. The instance is not the issue with Pagespeed at least not the way you describe it 2+ GB instances eliminate Pagespeed errors is a misassumption.
In fact this seems highly tied to key commands when editing within the Website editor specifically. This is not normal, Pagespeed flags on almost all CTRL+(key combo) to copy/paste, create a link etc.
Odoo plugin's are only the base plugin's at this point. CRM, Website, Sales, Invoicing were the ones installed.
These are not third party so the assumption of the instance and memory being directly tied to Pagespeed is not correct.

This is the last error and I can have it reoccur whenever I'd like simply by using Key commands within the Live editor to start. Not just CTRL, this is also happening with the "undo button" and various other controlled commands.
