Please send us your log files so we can give them a look. This has been happening occasionally. The aircraft switches from NaviGo mode to ATTI mode for no reason. If you didn't accidentally flip the PAF switch out of F to A mode this is likely what a few other users have experienced.
DJI says it is caused by a loss of GPS signal which puts the aircraft in ATTI mode.
