08 Yukon No starting power

[biggmac4]

I have a strange starting issue that has happened twice in the last 4 weeks. I have a new battery , Alt has been checked twice and is charging . Ill drive for a short distance, turn car off and then end up needing a jump start to get home. Then like I mentioned ill get home and the thing starts up like nothing ever happened with both Batt and Alt test showing nothing wrong. Is there mabey a relay or something that might need checked? Any info or experience with this issue would be great, thanks!
