Sounds like a clog. Which filament are you trying to print and at what temps? Normal or high temp extruder?

PLA will clog your high temp extruder for sure, it's only meant to be used with PC, Nylon etc, it's not compatible with PLA. If it's the normal extruder you may have to clean the extruder, it's also possible some filament is stuck in the gear which will make it slip so it's not extruding.

Also, make sure your extruder cooling fan is working. If it's not you can have that issue (if so, PCB failure likely).
