This is the third thread you've started about this machine problem. Have you read the replies in the other two?

If you developed a Large Leak during the night and it went for 3 minutes depending on the machine settings it would shut off and leave blinking lights.

That leak can be from the mask cushion being dislodged from the face and air escaping or you developed mouth breathing if using a nasal interface. When you mouth breathe CPAP pressure enters the nasal cavity travels back behind the soft palate and escapes via the mouth. Since there is no splinting ability with that your therapy is ineffective.

To test this, put on your mask where it for a couple of minutes and simply remove the mask then time how long it takes for the machine to respond and what does it do say after 3 minutes of leaking like that?

Via setup programming, you can set up the machine with Auto:Off, enabled or disabled. Disabled it sound an audible alert during those 3 minutes but it doesn't shut off. Enabled no alarm sounds and it shuts off and leaves flashing lights.

If you had a power failure and it zapped your machine it should be giving an error on the LCD display. Unplug it and plug it back in and see what it does.
