Sure sounds like an electrical contact problem. Did you also clean the contacts. If the connection is tight but the contact is oxidized or dirty, it will still have high resistance. There is a lot of current flowing when you are starting and you need clean tight contacts. Once the bad contact arcs, it will make the problem worse and then you lose power. I guess you can never discount the fact that it could be internal to the battery as well. Next time it is dead, don't touch anything. Leave it dead and just measure the voltage across the battery terminals. Measure directly on the terminal, and not the connector. Hope this helps.

sounds like you have a issue going on with the ignition switch

That "Click" you hear is the starter motor. When you turn the key it just clicks and that is it. Your starter motor is not getting enough juice, so we can divide this up into one of two problems, 1) your car battery may need to be replaced as a cell or all the cells could be dead, which is not giving the starter motor enough CCA (cold cranking amps) to kick over or 2) the starter motor is gon(ing), it could be as simple as the bushes inside the starter motor are worn out. I would try a different battery first and test it out for a few days. If it fails again, you may want to also check your alternator, to make sure it is charging. That can be done when you take it in to get your starter motor looked at.
