For a week now netflix has been losing connection while watching. What is going on

Could it be possible that you shared your account and password with a friend? If they are constantly connected it can kick you out. Just a thought

There could be several reasons but with so many on list, 1st check the wifi or internet connection, if it's low in bandwidth then that's your problem, if on phone or tablet, re-install app, if on pc or laptop, browser recent plugins, but the most common is the wifi router, when routers are going bad that could happen also, cable connections from out of home to inside, I mean the list is countless, but hope you get it back working.
