I have a MY23. The last week my A.S.S has been and stayed off! Gauge cluster shows off (button doesn’t) but it’s staying off. Lucky Fluke?

Mine has stayed off all winter and just recently started working again occasionally. Certain parameters have to be met for it to be enabled.
What's your battery gauge read? ASS is one of the first systems sacrificed to preserve battery. Can apparently stay off for some time.
I wish I could make mine default to off.

^^This, exactly what happened when my Raptor battery was low, stopped working until battery finally got low enough for other systems to start acting up, took it in to dealer and they replaced battery and all went back to normal (unfortunately ASS started working again as well).

This, during the winter it rarely activated and turned off until the car was well into the normal temp range. With the warmer weather here and there it has started activating more often. Aside from the loud/cheap sound of the car restarting I absolutely do not understand the hate for the auto-start-stop.

there is a sequence where you can disconnect the door connection plugs (when you remove doors) and reconnect them and the A.S.S will stay off until you open your tail gate door. There Is even a sticker in the driver’s door jam that says that doing this will affect some of your engine controls (although it doesn’t say exactly what controls). Not sure if it may have came disconnected on you and this is what is causing the A.S.S to stop working. There are other things that could keep it off, like air conditioning running, outside temp, stopped on a hill, etc, but that doesn‘t seem to apply to you.
If you use your R mode every time you start your raptor you can save it with the auto start/ stop set to off.
If you haven’t found it, the up/down arrows on the steering wheel moves those screens. The last (first?) screen in that sequence provides instructions how to get the screens up.

There is also a battery state-of-charge parameter (apart from just Voltage, although you can kind of infer that if your Voltage is being kept high for long durations that it's trying to recharge that back up) that you can't see on the dashboard that feeds into if ASS is enabled or not. This is what usually causes it to just randomly stop, especially if you do a lot of short trips (and when the battery charges itself back up, or you put it on a charger, it randomly decides to come back).
Along with a long list of things that can shut it off - here's a list one guy compiled (this was from F150 forum, but I can't imagine it being a lot different)
Steering Wheel Manuevering
Battery Charging
Cabin Climate unsatisfactory
Ambient Climate isn't Moderate
Selected Gear (4x4)
Selected Mode (Sport, Baja, Mud)
Windshield Defrosting
Primary Seatbelt not fastened
Door Ajar
Incline / Decline too Steep
Elevation exceeds 11,000 ft
Insufficient Brake Vacuum
Normal Operation (if you stop, then proceed without exceeding 3MPH then Auto Stop Start is still disabled)
Engine Temperature
Trailer Connected
Selected Manual Transmission
Hill Decent Control Active
