How to keep Firestick 4K alive when watching another TV input?

[dannykewl]

Hi, I have the newer Firestick 4K, plugged into one of my TV's HDMI ports. I also have an OTG cable with a thumbdrive in line with the Firestick so I can have it record thru an app what's streaming to watch later on my PC while I'm using something else on another HDMI input on my TV, usually my PC. When I go check, the Firestick is completely off, blank screen, and find out only a few minutes recorded, This happens whether I use the OTG/thumbdrive, or just have a normal connection of the Firestick into an HDMI port. If I have something on the Firestick, then go to another HDMI port to watch something briefly, then go back to the Firestick, it's still working. If longer, the Firestick shuts off. I tried looking for settings to keep ot awake, and nothing. I even side loaded a Stay Awake type app, and that doesn't help. How do I keep the Firesick awake and active? Thanks.

Why oh why do you think this setup will work? It will not work as you intended.
Ok. Question 1, what are you wanting to record off the Firestick?
Your limited to only certain streaming apps here....

This does seem to be something of a convoluted setup, using a mix of devices that work well at what they do but may not be, by design, intended to work the way you want to re-purpose them to do.
