Default Battery, Alternator, or a Battery Drain?

Howdy...I am new to the group and a "fair" mechanic meaning I do mostly simple stuff but I have a problem I'm not sure how to resolve.

I have a 1992 GMC 2500 Sierra 4X4 with a 454. The other day my wife was sitting in it listening to the radio with the engine off for about 20 minutes. Never had an electrical problem with it all but the next morning it would not start...I had to jump it off her minivan.... I could jump start it drive it an hour to work and at the end of my 10hr shift I would need another jump; and the same thing the next morning. After a few days of jump starting it I bought a good strong battery with 700 CCA. The next morning after installing it started and drove the end of my shift it was dead. My volt meter reads just shy of 14 volts but it has always read that.

I started disconnecting my battery when I park it, but today I found that if I disconnect the positive cable from the battery while the engine is running it will continue to run until I kill the ignition.

Any help or advice is appreciated...

I think your battery would be affected due to moisture due to which such type of problem been occuring.
