Hi,  
  
I have had my 93 Impreza for a little over a year and I have replaced the water pump, timing belt, alternator, starter, battery, batterycables, fuel pump.  I am now having a problem that I am not sure what it is.  Recently i went to go somewhere in my car and the car was completely dead.  I got a jump and it started, shut it off and dead.  Got another jump let run for 45 minutes and while driving it just died.  No power what so ever.  Put in a new battery.  Ran good for a couple of days and dead again.  I don't know what it wrong.  The battery cables are new, the battery is new, it is grounded, all connections are tight.  What is it?  Help me, please!!!!!!!!!!
