First thing I would do is take the battery to where you bought it (or autozone) and see if it holds a charge. Secondly, have your alternator checked (even though you say it was just replaced... it still could be bad)...check your battery cables (positiveAND negative) for cleanliness... have your coil checked lastly.

After you do what SlamminMOfo recommends, I would check the current flow with the ignition switch in the off position, possible short and high current draw.

It was a bad alternator...had it replaced again! Now the cars main problem is the miss in the engine that no one can diagnose
