Time Lapse mode keeps turning off.

[Usually Unfocused]

I'm having an issue with time lapse mode. The camera keeps turning itself off. It seems at at least one cause is momentary loss of USB power. But I think I've configured it to ignore same:

Power on=[1];set system  power on time,0:delay,1:fast
Power off=[1];set system auto power off time when system pending,0:off,1:30 seconds,2:1 minutes,3:2 minutes,
Auto Record with External Power=[0];set connect with power to start video recording automatically,0:off,1:on,
One Power Button to Auto Record=[0];set press power key to start video recording automatically,0:off,1:on,
Auto Off with External Power disconnected=[2],0:Immediately,1:delay 10s;2:record to low battery power off,

Does anyone else have this issue?
