Android box turns off while using Kodi

For the forst 2 weeks that i owned my leelbox MXQ pro mini everything was working perfectly but recently my android box keeps turning off on me while using kodi, it happens anywhere from 5minutes to 3 hours in. And after it turns off it will sometimes reboot on its own but usually my remotes will not work so i am forced to unplug and replug in the power cord before i can turn it back on. Any ideas that could help are greatly appreciated.
