I had the same problem in a Buick I had. It was caused by a problem with the computer, which had to be replaced. At least that's where I'd start looking. It causes a low constant drain on the battery.
wouldn't start at the computer more than likely something simple like a diode in the alternator or trunk light switch maybe hood light switch start with the cheaper things first

I've run into that problem also and when I checked, there was enough moisture from positive to negative posts to drain the battery. And check loose wires from and to the battery. Nothing? Put your car in the garage at night, turn off all the lights, let your eyes get accustomed to the dark and look under the hood for any evidence of any amount of current. I've done that and found the a couple of times.
That would be a 4L60E
That would be a 4L80E
1972 chevy cheyenne 10 super with 400 big block price will be at price of 19,900 $
I would suggest a new set of plug wires.
It would depend on what year. The newer ones are self adjusting.
$50
That would tend to indicate that the alternator was not charging the battery for that interval.
Have the battery and/or starter tested for free at your local auto parts store.
it indicates that the alternator is not functioning sufficiently to keep the battery charged.
Could be a shorted wire, or bad battery.
The type would be the one that belongs in it , is there no battery or auto parts store that you have in your neighbor hood
Under the hood by the battery, if it was a snake it would have bit you
