Hey -
  I have a Plymouth duster.  My car does the same thing - I've taken it a couple different places and the best hypothesis they have is that when the fuel tank gets low (half or less), air is getting into the fuel pump causing it to stall.

Simple test will rule out the fuel pump.  Disconnect the line at the filter located under the car near the rear passenger door.  Prime the fuel pump (turn the ignition on but dont crank) have someone look at the flow of gas.  If its a steady gush then the pump is fine, if it sputters out then it's the pump.  Now best thing to do is go to the  ignition coil, pull off the wire from the distributer cap and put the wire about 1 inch from the block or the frame, depending on how long your wire is.  Now have some one crank the motor, if you dont have a spark then the coil is not sending any power to the cap, and the plugs are not getting spark

I have the same car and it is a common problem it has nothing to do with the fuel pump what it is the carborator clogs and you have to clean it the valve sticks I'm not sure how but my dad does it all the time because i have that problem alot.  also try a Can of chem toll B-12 in the gass tank that helps clean it and keeps it from cloging

I have a 94 Shadow ES and have done extensive research and work on my car. If it's idle related, check timing, check throttle adjusting (pop cap off stock TB and use a star key to open it up a little. If it works then you've established the Throttle position sensor is not performing correctly. The best thing is to remove the plenum, disconnect the Throttle Body, clean them both VERY well w/ carb cleaner and pick up a new Throttle Position Sensor (TPS) from the junk yard (any 92-98 Chrysler 3.0,3.3, or 3.8 engine). If this is not the problem, it may be sensor related. (MAP, EGR valve, etc.) Only sure way is to hook it up to a computer than most any mechanic should have. That's the purpose of sensors. To monitor and run the engine and send any odd readings to the computer to store. These codes (numbers) the computer recieves are called fault codes. Good luck.

Same car and it did that once for me and it just so happens that the tank was near empty.  I also have a otc 2000 series scanner and all my sensors are good.
