Old thread, but it was most likely the MksPi CPU in the Klipad overheating and triggering a shutdown rather than something software.
You can add monitoring to the software or a cooling fan (I did both here: The Sv07 is still an amazing deal... but here is how you fix a brand new one), but for a simple “hands off” test if that was your issue, just take the screen off the bracket by sliding it upwards to expose its vent and aim a powerful fan at it, try a long print. If you no longer crash, you have your answer.
A lot less drastic than taking anything apart or flashing firmware, where a stuff up will turn your printer into a paperweight, and even if you don’t make it worse you’ve cratered your chances of claiming warranty for a defect.
