    I've got a mindfreak going on with my 97 LSC.

    It spends a lot of time sitting, sometimes weeks at a time. The past couple of drives have gone like this:

    -Start car. Take a 5min "dust off" drive around the neighborhood. Park it.
    -Start car 10-15min later, take it on the joyride I intended. 20-30 min, WOT a couple times, fun fun, engine gets up to temp. Park it.
    -Try to start car less than 5 min later, and:
    --- Dome lights come on as normal when I enter
    --- Dash lights and dinging come on as normal when I click the key over to accessory.
    --- When I try to start, a loud click comes from the engine bay and *everything* dies, and stays dead. Key in/out/in/out nothing, a lifeless car.

    That battery has 12.5v, but electricity isn't getting from there to anywhere else.

    The first time it happened, I was at the grocery store. I came back 4hr later to jump it... but didn't need to. Started right up.
    Happened yesterday in my driveway, so I could experiment a little bit, none of this worked:
    - knocked on the starter with a hammer
    - shaking the car and slamming the doors (loose-wire theory)
    - Pulling various fuses (reboot EEC theory)

    I would notice that after a few minutes (I'll put a stop watch on it next time), the car would wake back up: The dome lights and everything would come back to life, and everything up to putting the key into accessory would be normal.... but, try to start, and there's a Click from the engine and everything goes dark again.

    Wild-card: After waiting for the car to "wake up", I entered the car from the passenger side, stuck the key in, and it started right up.

    Special note; the aint-theft light has been blinking since I've owned it, close to 5 years.

    Anybody have any ideas on what's broken?
    Thanks in advance

    sounds like a loose or corroded battery terminal

    New battery, new'ish terminals. Hooking the jumper cables directly to the wires (bypassing the terminals) had no effect. Also did a cursory tug and shake on the battery wire bundle, no effect.

    Check the other ends of the battery cables, and the ground strap to the block.
