Help 1971 Chevy C10 in pain

[virgilfarlow]

We just bought a very rough 1971 C10 pickup the motor has been changed it was a standard now its a automatic. Was running when we brought it home, then that changed. It would start take us where we were going but when you shut it off and went to restart it no way, it wouldn't start back. Tonight I drove it to work after putting a brand new battery in it ,all seemed fine, when I left work 11p.m. it lost power then died and would not restart, I had to spend 50 bucks on a tow truck. It wants to run and be born again I just know it but my mechanical skills are not the greatest between my wife and myself we thought with a little help we could pull it off. Anyones got any helpful tips or suggestions we are all ears. Thanks guys
