Default [Q] AOKP random reboot

hey guys

I have AOKP 4.4.2 and it's awesome but my Phone keeps rebooting about every ten minutes. I have seen other people with this issue too. I am not overclocking my processor, so i don't know this is happening every time. I also tried reinstalling it but still.. I tried other roms (CM, Omni, Carbon) where i don't have random reboots at all. Please help me!!

Also i have an unofficial build (by NovaFusion) for the Galaxy S3 mini

Thanks
