Was this with GPS or in atto/manual. If in GPS it may be a bad connection to GPS antenna or loose antenna. Try w/o GPS antenna if connections seem OK.
If in Atti/manual I would not risk flying it, contact your dealer.
I had a Naza go crazy on me last year and DJI replaced it and then everything was fine. In my Naza case the gimbal would start swinging wildly and then it became very hard to control the MR.
You can try hooking it to the assistant SW and updating everything, then testing with props off to see if you have proper control. You can also after updating clamp the MR to a table and check correct operation with props on.

If you can't troubleshoot this issue successfully on the workbench.... remount your IMU and controller on some anti-vibration "Zeal" tape and fly it again. If the issue disappears, it was caused by MR airframe vibration.

No..... mine maintained totally level flight.....only vertical control was lost..... but there is no way to predict which input sensors will fail to provide correct data to the IMU when there is excessive vibration.
