Truck stalls and battery keeps dying

[Stevegt]

I went away for a week and when I came back I started my truck turned out of my driveway and the truck stalled, started it up again but truck kept stalling, it stalled while driving for a few days now it stopped stalling but the battery keeps dying, sometimes the battery will be completely dead in the morning, I'll try again at night and it start up. Any help will be appreciated.

Thanks

Disconnect batteries to check if the batteries are shorting overnight. In my opinion, batteries in H1's should be changed every 3 yrs.
Stalling could have been a PMD issue or a faulty fuel pump. Some will run even with a bum fuel pump while others will not. Start here and report your findings.

I am assuming an H2 as it says in your sig. Either way it seems like either your batteries of maybe your alternator are going out. I vote batteries. When you draw down the batteries past the 10v mark often they will not recover and will never fully charge after due to sulphated plates in the battery. Further, the PCM in your truck may have brown outs due to low voltage and the truck can stall as a result. Try charging the battery while disconnected from the truck and see if it helps. If not, i think you will need a new battery and a trickle charger to keep the charge up when you go away for longer than a few days. On my truck because of all the mods i can bleed down my batts in a day so i have to have it on a charger or i would be going through batteries like penut butter sandwiches.

as mentioned above its either the alt or battery.
please report findings as I'm sure many are curious.

I'm going to change the battery and I'll keep you guys posted, should I stick with te acdelco battery? or is there something else you guys can recommend?

No real difference on the battery. Now is this an H1 or H2?  You have truck type as H1 and H2 on listing.
Did you disconnect batteries to see if they are holding a charge? or is it a draw in the system? Check this first .No need to spend money the wrong place.

It's a H2, Sorry need to change that in my profile. I ended up buying a new batter about a week ago and the truck has been starting without issue, I'll keep you guys posted if anything changes

The battery terminals corrode on those, and if it sat for a week it could be as simple as taking the terminals off the battery and cleaning them. I think the early h2's have those dreaded side post terminals. If this is the case once off the battery you will need to pop the bolt out and pull the plastic shiething off to clean them properly.
