2001 Tahoe Battery Connection?

Every couple months my Tahoe battery connection just stops working. The general problem description goes like this..
1. Hit key fob and doors open and lights work in the truck.
2. Stick key in and turn ignition. Everything dies including the lights and doorlocks. No clicking sound coming from starter. No nothing.
3. Open hood and physically wiggle the positive battery connection. On Sunday I disconnected the battery connection and took a wire brush on the connections (both battery and cable). There was no visible sign of corrosion. On other occasions all I do is go to step 4.
4. Reconnect or tighten battery connection.
5. Crank truck. Truck generally always cranks, but will sometimes cut off once RPMs raise then drop (blip the throttle). If that is the case then I tighten the battery connection even further and the truck will remain running.
Battery is less than 2 years old and is a OEM replacement (Delco purchased from Chevy dealer). I don't think it is the battery as I have had this problem intermittently since I purchased the truck 5 years ago.

So my question is how do I fix this issue as it never happens on a Saturday when it is 70 degrees/sunny and the truck is sitting in the driveway.

Generally it occurs every couple of months (including the summer so it is not only related to the cold).

Deryl,
I seem to be having the same problem. I have a 2002 tahoe. With a fresh battery everything seems to work fine. Slowly the battery begins to drain. a charged battery will last about a month or so depending how often it is driven. I did notice that once I turn the vehicle off, the inside courtesy lights stay on for about a minute or two...normal. Then after they go off the dashboard high beams and cruise control lights click on for no apparent reason about a minute later. No key in the ignition, doors locked. It sounds like there is a short somewhere that is causing that system to click on and drain the battery. I took it to a shop and they said it was the battery cables, yet the battery is still draining after changing them out and making sure the connections are tight. Let me know if you have any luck.

Just to follow up with this, i found my problem. It was the radio (Factory) that was draining my battery down. It seems the outputs were shorting out. It was funnny that the day before i couldnt turn my rtadio off, turn it up, change the tuner,or nothing.

My 2001 tahoe LS is doing the same thing. I discovered that it is the RDO Amp that is draining the battery. If the Truck sits for more than two days then I have to recharge the battery. I have found the problem but what is the solution? If anyone has figured this out please let me in on the secret. Thanks

I have this exact problem. Others have posted having "the same problem" below, but they do not. This is not a dead battery. The battery is fine and it is not drained. I can't figure why this keeps happening every few months. I have cleaned the contacts, put dielectric grease in, and even replaced the battery. Sometimes I get the car to start, but it will stall if you don't keep your foot on the gas. Further futzing with the batter contacts and adjusting stuff and that problem goes away.

Hello, I have a 2002 Chevy Tahoe and I am experiencing the same thing. Battery drained after vehicle sits for 1 complete day. It seems to be happening more frequently now since it has gotten colder. Before the weather changed, I had no problems with my Battery. Could the weather also be a factor?
