I have an ender 3 that sometimes will just randomly pull all the filament out at the beginning of the print. I have been just stopping the print, resetting the filament, and restarted the print and it works fine. what could be going wrong? any ideas

What do you mean by "randomly pull all the filament out"? It's normal for some to ooze out as the nozzle heats up. The printer will then "wipe its nose" at the side of the build platform before starting the print. I doubt you mean that though. Maybe a video would help.
To be honest though, 3D printing seems to always involve something randomly going wrong. If that happens occasionally then you're probably doing it right.
Not sure root cause, but I'd recommend doing basic maintenance to see if that fixes the problem - teardown the extruder, meticulously clean out all the filament pathways including the nozzle (maybe even replace nozzle if old) , wiggle and reseat all the extruder connections.
1. What software are you using to produce the gcode your printer's using?
2. What's the GCode look like that you're using for the print? Would you share it?
3. Does the slicer software you're using have a 'start up' gcode that may be messing with this?
4. What's practically happening when this occurs? Are you able to take steady video footage and share it?
This information would be really helpful.
Cura slicer, standard 0.2mm settings, no changes to start up, I'll work on getting some footage
I use Cura on an Ender3. Haven’t personally experienced this issue. Are you using the stock Marlin firmware provided with the printer?
The extruder will run in opposite direction pulling the filament from the hot end.
I have flashed the firmware to TH3D. I know someone else with the exact same setup and has not had this issue.
