H2 Stalling when stoping?

[Roberts0341]

I have a 2005 H2 and a few months ago had a issue with it stalling out at a stop. The rpm's would slowly drop down and it would shut off, it would restart with out issue. Its not one of our daily drivers so I let it sit for a few months in our garage after having this happen a few times until I could get it into our shop. I'd drive it around the neighborhood every once and a while and it would still stall, Of course the battery drained over time while sitting. I'd charge the battery but not very long and drive it around the neighborhood and it still would stall out. The night before I took it into our shop I fully charged the battery over night, and when taking it in, I did not experience the stalling issue once. They say the battery is weak which I knew it needed changed but do you think the stalling issue could be as simple as a weak/dead battery? I was told by a friend it might be a fuel pump, any help would be appreciated Thanks.

If course it could be the battery, it could be the alternator too, or maybe something as simple a bad/dirty gas. I'm sure others will chime in with more ideas.

Thanks, I was thinking that after they said the battery was low, maybe its not getting enough charge from the alternator. Also was thinking of cleaning the Throttle Body when I get her back today.

Any auto parts store can do a battery check for you for free. I would start there. Alternator or possible vampire power drain from somewhere could also be the culprit. Any aftermarket alarms or other accessories installed?

Cleaning the throttle body is always a good idea anyway.

No all stock nothing added aftermarket, I got Her back the other day and she ran super strong this weekend out in the woods. Im guessing it really was the battery. We also got the 100K service done early as well. Was thinking of replacing the altanator and cleaning the throttle body.
