Well I think I solved my GoPro problem. And it makes sense. Google search shows that if I do not use a high speed, Class 10 memory card, it will do the exact same thing it is doing because the slower memory cards cannot keep up with the GoPro high speed write. I have to look for the original memory card and reinstall it to verify. I didn't think to check if the new card I got was a Class 10 when I bought it, and it's not.
