Have someone check if there’s a parasitic current draw on the battery as the vehicle sits.

Maybe you need a new battery?
I recall a similar “mysterious” problem with a Lincoln parked on a steeply sloping driveway. In that case, the trunk light switch (a mercury filled switch) was defective. On the level it was off, but on a slope it made contact and the trunk light drained the battery.
Agree that there should be a thorough check for parasitic drains.
