Default 2000 GT - Battery dies, but isn't dead?

I have a 2000 GT with 154,000 and a manual tranny. Over the past three weeks, my car has just died when I attempt to turn it on (it's only happened 3 times in that time span). What will happen is I put the key in the ignition and turn it to run for a second, then I turn it on. It is at this time that I get a "POP" and all power goes away. I found a quick fix to it, however. If I remove the positive AND negative battery cables for a couple seconds and then put them back on, my car works fine. My dad and I have replaced the battery terminals with cheap AutoZone generics. The old ones were nasty. It almost seems as if there is a short in the cables somewhere causing the battery to just die. Well any help will be greatly appreciated! Thanks.

I would look along the new lines and see if there is any evidence of arcing or burnt areas. That's where I would start.

The odds favor:
  • bad/corroded battery cables
  • bad/loose battery terminals.
  • bad/loose main battery terminal at the battery junction box
  • bad/loose radiator core support ground.
Note, it's unlikely there is a short. Why? Becase much of the main battery power cables are NOT fused. So if there were a short, there's nothing to stop it until either the cable burns up or the battery dies. Since the battery isn't dead, that points to an "open" in the circuit.

Thanks for the info guys. What actions should I take when checking the radiator core support ground? And where exactly is the main battery terminal? Also, how should I go about changing the battery cables? Do I buy new ones? or just make them not look like a big jumbled mess?

Are you wanting me to post pictures? If so, what of? Or do you mean you're posting the pictures? Sorry, I'm just a little confused.

I may be all wet, but I think the problem is in the battery terminals or cables. I was hoping that if you posted pictures of the battery terminals we could see if they are really clean and tight.

Be sure to get a good picture of the battery negative terminal since it's bad about breaking if over torqued.
