Has anyone had there video stop recoding during a flight session stop randomly for no reason?  I have tried My record settings at .mp4 or .mov in 4K 30fps, and it stops randomly after a 1-4min.  I have plenty of space on my SD card, and the make is a sandisk ultra plus 64GB. I also made sure i was not accedently hitting the record button to stop.   

This might be a side effect of the Ultra SD card not supporting the write speeds necessary to record at 4K. Does the same thing happen when you drop the quality to 1080P?
