Yes, I believe it's that 20-25 minute wall that we are hitting and seeking a means to avoid. At least that's what it is in my case.
Surely the OP and I cannot be the only folks old enough to remember cars where you just turn the key in the direction opposite that which starts the car to turn on just the radio (no fans, no lights, etc....) and the radio would stay on until you turned the key the other way or the battery ran out??? You might think of it as "drive in movie" mode.
