A faulty capacitor, or, if you're lucky, an intermittent contact.

See here and here.

Thanks!
I should emphasize that it stays on for much longer when the batteries are fresh. The problem is that it went back to turning off too quickly after just two days (or less) indicating to me that the batteries are being drained. Would this indicate an intermittent fault?
