I just noticed I'm having the same issue only it seems a lot more often and for longer duration. I'll get a few minutes of recording hours without then a few minutes. I did not notice this with the Thinkware 32 GB dash cam card that came with the dash cam but with the Samsung Pro Endurance 128 GB which was supposed to be a top rated card. I will switch to the Thinkware and see if that resolves the issue.
