Printer is not feeding and stopping extrusion during print

So as the title says, I have a printer (gMax 2) that is just not feeding continuously while printing. Really needs to be babysat which is a huge waste of my time. It'll print for say, 45 layers and then suddenly its just going through the motions, not feeding. This is with any filament I try, it just stops feeding. I've cold pulled the hot end, that came out clean. I'm at a loss.

Any help that can be offered urgently would be appreciated.
