I object to my printer, I have an Ender 3
lol I object to it too :-)

Sounds like you have a gap between the ptfe feed tube and the top of the brass nozzle on the hotend.
This causes the machine to start exrtruding and a pool of molten plastic graducally builds up in the gap and the filament stops extruding.

It can be as simple a fix as pushing the bowden tube a mlot harder into the hotend.

Or as awkward as dismantling the hotend, cleaneing it out and making very sure the tube reaches the the top of the nozzle.

It could be a bunch of other things - but the bowden tube into the hotend is the first place to start.
