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 $
It would depend on what year. The newer ones are self adjusting.
I would suggest a new set of plug wires.
$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.
5-30 in the summer is recommended. If you have the money I would run a Lucus oil stabilizer.
difference in a cheyenne and silveradoChevy cheyenne was a lighter duty model,normal difference would in the frames thickness and suspension capabilities, the silverado was made on a heavier frame and the rear gearing might be a little different to allow for more initial torque when towing a heavy load or when hauling, being as how the silverado it consider the best of the Chevy truck series, for towing, being beat by only one other on the market... the Chevy Suburban which has been the leading vehicle on the market for years as perfoming the best when towing....
Could be a shorted wire, or bad battery.
