The battery sometimes drains after sitting for a few days/weeks (most recently 2 weeks). Only the dash lights come on and you hear the clicking sound.The original battery has been replaced and now, after about 2,000 miles on the new battery, and driving the car a few blocks or miles every 2-3 weeks, it's started doing it again. Can't find anything that's obviously on when I search inside the vehicle.

More than likely you have a what is called an ignition off draw. Meaning something is coming on with the key off that is draining the battery. I attached the steps to test this.

Also, here is a guide that will go over some common things that cause this but I suspect you will need to run this test to find the issue.
