Feeding issues CR-6 SE

When printing, everything seems to start out fine, but then the filament starts to not feed properly. The feed sprocket starts grinding because it there isn’t enough force to push it through the nozzle. It ends up short feeding, and eventually just plugs all up.
I’ve tried turning off cooling, turning off retraction, playing with temp (up and down).
