noticed strangeness in graph in Sleepyhead

I'm running bi-pap 19 IPAP / 14.5 EPAP

Recently at least 2 times a night for the past week, Sleephead is showing a very rapid pressure (mask pressure too) drop from 19 down to 4 and then an almost immediate return to the set pressures.

FYI --My ramp time is set for 5 minutes... whatever is happening is so brief that it isn't triggering ramp to start up.

I'd normally attribute it to my mask pulling off my face for an instant, but there is no evidence of massive leak spikes in my charts.

Leak levels on the graph seem to be perfectly normal for me.

RESCAN shows no evidence of this occurring at all.

I am beginning to wonder now;

Is it possible that I'm briefly losing power?
Or is maybe the power supply for my S9 acting weird & starting to fail?

thoughts?
