Tahoe fix

Well I want to come to town in the next few days to go thru my room at my mothers before her ex-husband moves in and tosses all my stuff. But what I am waiting on is for my boys to fix the Tahoe so that it doesn't die at random times like praying it starts every time its turned off. I need the bigger car to move stuff. My guys are hoping its just the battery not something more serious. I will also be organizing a garage sale hopefully with my sisters help. So if anyone wants to add stuff that live in the area just let me know. And yes Little man will be coming with me.
