In any case if that amplifier is shutting down in an application where it shouldn't I would send it in after the season for a full check up.
The JL Audio HD amplifiers run full diagnostics within the first second or two after turn-on and adjust the rail voltage of the front and rear channels independently based on the respective impedance load. You won't find a more sophisticated amplifier. So if its shutting down it would take a low voltage threshold, whether on the remote turn on circuit or on the supply, or a damaged speaker voice coil that is changing its value after heating up. Thermal is unlikely since it accounts for an inordinate load in its initial power up process. And that takes me back to a factory set threshold that may need to be checked and revised. JL Audio did send out a memo on the turn on threshold for an HD model. No guarantees but it seems like a possible fit.
