I own an Alfawise U20 (CR-10 copy) since 2018 and I'm having exactly the same issue as @classified.
No need to say I did the same you did (new bowden, new hotend, new nozzle, new thermistor, new heat resistance, new fans, checked all belts and motors, ...) and the problem remains.
My prints have very good quality until suddenly stop extruding. Already tried diferent/new PLA filament (I only use PLA). I even checked the mainboard and all seems ok and normal.
When I say stop extruding, it really doesn't extrude any filament, no incomplete extrusion or strings. Extruder motor still running, filament seems to be pulled, not slipping on the gear. I already put some washers on the extruder arm spring to push the gear a bit more.
I already asked for help on the facebook Alfawise 3D printers page with no success.
Maybe you could be my salvation!
@GregValiant you seem to be a master user. Any advice/hint?

Hello to you all!
Well, it seems my time came.
