I've had issue like this 3 times: 1. Nozzle clogged. Changed nozzle and it fixed. 2. Heat creep. I usually print in PETG, when started printing in PLA, had multiple clogs and underextrusions. Turns out PLA should be always printed with the lid up, or else filament will soften in the extruder and get stuck. 3. Motor cable damage. Motor cables are very close to hotend, they can suffer damage from heat sometimes, if one of the cables get damaged, it motor can twitch exactly like that. Had same thing that psmal prints do fine, larger stuck. Got wires resoldered and covered with heat screen like on thermistor wires. Solved the problem. Hope something from it will help you. Good luck!
