96 Blazer 4x4

I bought this thing used. They had to end up ordering me a rebuilt transmission about a year later. It has a brand new battery, but we have to jump it when it's cold. Drove it today to the store and everything just went dead..EVERYTHING..can't jump it. no lights no gauges no nothing. Any ideas? I'm really sick of this blazer, I love it but it's been nothing but problems since I got it. Thanks for any help you might be able to provide. :banghead:

Welcome to AF on your first post.
It is time to get out a volt/ohm meter and check for where it is losing 12 volt power feed or ground.
Start at the battery and cable ends and then work up to the fuse/power box.
And do not forget the grounds.

alternator?
