i had this happen when i bought my ender 3 max "my first 3d printer" and discovered that I did not level the bed correctly leveled forcing the print nosel too close to the bed not allowing the plastic to extrude properly, what material were you printing pla, abs, petg? if your printing a higher temp plastic like abs and petg those plastics are prone to warping and after 15 min of printing you may have had the print warp and mess with the distance from print nossel to the print causing the filament to start skipping
