Alternator. It's not charging correctly. That's all bud.

 

As leviA says dud alternator.
Is your ignition warning light working ok, cause if the bulb goes it will not charge.

I only know because I had the same problems on my old XR2, car was erratic, lights dim, backfired, conked out.

All from an alternator!!! A lesson I'll never forget!

 

Sounds like it could be the alternator, but your battery will probably be ruined from continuously being flattened aswell.

A charging rate test and battery test would be a good starting point.
