Vsett 10+ 30 mile Three city ride. GoPro farewell?

First, not sure why my video was small.
The problem is on the GoPro
When its recording, it just cuts off random.
Usually when i hit the record button, 2 seconds later it turns off.
When I turn it on, it is repairing the file. Does that many times.
It does that on many SD cards I own. I don’t know why.
