Typically, recording issue is correlated to either a problem with the SD card being used, or the camera itself. Try using a different SD card (if available). If it records fine, then the issue is likely stemming from the SD card.
You can get the full list of microSD cards that are known to work well with GoPro cameras here.
It is also advisable to format the SD card before use. (NOTE: Reformatting the SD card will delete all data off of the card, so be sure that you save any videos or pictures you want to keep on your computer before reformatting the SD card.)
Reinstalling the firmware update of the camera can also help correct any errors with the current software installation. Follow the manual update instructions specified on this article: https://gopro.com/help/articles/block/How-to-Update-GoPro-Cameras
Hopefully this helps.
