I am trying to answer this without being majorly sarcastic, however I am English so I shall be sarcastic at the end
It sounds as if it is going into sleep mode and not waking up. I would look at turning off the sleep function. I always have my PC's with this turned off, the hard drives are always on, this would be in your power settings, you need to create your own settings, by default you have balanced etc.
Now for the sarcastic part
1) Using Windows 10 especially for a cabinet is like teaching Stevie Wonder to drive or fly a plane. You just do not do it. I was a beta tester for a lot of Microgreed's operating systems, 10 was brilliant until it reached the final pre release beta, and then it went to a crawl. I thought mmm, ok I shall wait for the updates and it was still awful. I went back to Windows 7, a couple of years later, I decided to give it another try because of wanting to use the xbox with it, and I re formatted back to Windows 7 in less than 24 hours, it was still that bad.
I will also that is it a spy ware, ransom ware operating system, which was designed to compete with the android market, where you download a FREE game, but then you have to spend £100,000 on gold just to complete the game. It really is a scum ware operating system.
2) Lunchbox as a frontend? Yuck even worse than Windows 10
3) Get a divorce, it is an ARCADE CABINET not a picture frame. It is like buying a home cinema screen, dolby atmos, and movie projector and having that as a picture frame, when it costs £500 for a replacement bulb. You just do not do it.
However, trying adjusting your power settings, getting rid of windows 10, changing your front end, before the divorcee, after all they are the more expensive option
