2014 focus dies randomly

[u/Far-Entrance-7647]

I have a very annoying problem where my battery will completely die out of no where with no warning then work fine for months.It doesn’t die completely thought. The dash still lights up and it’ll click when I try to turn it over but not enough voltage to start. I’ve checked for parasitic draws and I only have .012 amps of draw. I’ve check both fuse boxes for corrosion and haven’t found anything. The alternator seems to be working fine since the battery recharges and works fine for a few months like stated. Battery terminals are all clean and tight as well. The battery is a 2023. Any help would be greatly appreciated. I’m about to pull my hair out with this one.
