2007 Tahoe Keyless Remote problem

[Bigguy]

I hope this turns out to be a stupid question and is easily fixed.

After immediately exiting the vehicle, or doing anything with it, the keyless remote works fine. All the functions work like normal. Let the vehicle sit for a minute or two, and nothing works. You have to unlock it with the key.
I have "relearned" both remotes and gone through all the settings in the DIC to no avail. Both remotes work ( or don't ) the same.

Any thoughts?
Thanks
