Oldsmobile/Buick Repair: Buick Stalling, battery gauge, loose ground

Question
My buick stops when I go to slow down. My battery gauge drops and sometimes it recovers power before it shuts off, but sometimes it stalls but start right back up. It seem to stop only when a load is put on the battery. I have replaced my battery and alternator. I am fresh out of ideas could you please help!  

Answer
hi x.well first thing comes to mind is bad ground or pos cable.as long as you are sure you have a good alt.and it is functioning properly.a loose ground cable or even hot cable at the starter.also check for a link or hot wire moveing with the eng and possibly grounding out against a piece of steel or another wire check the eng harness very careful.hope this helps.please don,t forget to vote or rate us billymac
