Ender3 Problem

Hey! I'm new in this forum and also in 3d printing. Latelly I've tried to do a proyect with my Ender 3, a moonlamp from thingiverse:https://www.thingiverse.com/thing:3532973the problem comes when printing. It suddenly stops extruding filament without any clog or something, it also looks kinda weird. Other prints works but this one...Also it appears little drops of filament kinda burn
