Unknown electrical issue

[2012gen38]

I have a 2012 genesis 3.8 that has issue of stalling (at least I assume its stalling). The car has been sitting for about 5 months and I don't have much information as to what symptoms it was experiencing prior to it's sedentary state. What I know now is that I can start it when it is jumped, it will drive fine for a second and then everything will shut off. I checked the DTC and I have a bunch of codes related to the transmission. Electricals are a bit out of my wheelhouse so hopefully someone on here can help me decipher what it is I am looking at.

Alternator/Battery system. Seems like alternator is not charging your battery, or your battery isn't accepting the charge.

If it was fine before sitting, I would start with the battery connections. Also take the battery to Autozone (not sure where you are ) and have the battery tested. If it is good but low on power, have them charge it for you. When you put it back in the car be sure to check the cables and connectors and tighten them good. If the car runs, I would take it and have the alternator checked to ensure it is working.
