I think my Blazer is a hybrid. Need help.

[BLUE THUNDER]

I posted some time ago that my Blazer battery dies every two weeks. So, I jokingly call it my hybrid because I "plug it in" every couple of weeks. I got pissed today and pulled all the fuses to the things I don't use. A/C, radio, heater, and a red wire on the spade connector on the unfused terminal. I've bought a new alternator and voltage regulator, as well as new frame ground and made sure the braided grounds under the hood are bolted down. So wth? What else should I do? Could it be the starter? Are there any other grounds I should check? How else can I diagnose this issue? Btw, new battery as well.
