Could it be that you are low on ATF? ATF shrinks when it is cold and expands as it warms up.

As suggested above,i would start by checking the ATF level.
Was the fluid flushed recently?If so,was the filter replaced?
On my X it all started with 2nd to 3rd slipping,but sometimes it wouldn't move even in 1st but that slam into gear really bad.
Within 1000kms from a partial flush(just a half fluid volume) I ended up with the Torque Converter shuddering at 40-45 km/h.So,if you start some slight shaking at low speeds,then you have to get ready for a rebuild.
Another thing that throws failsafe modes is a bad battery,or alternator.
But it has no certain pattern,I've been there too,so if your box is behaving the same way under certain conditions,then it's a mechanical fault.Unfortunately.At least I would think so.
