is your idle dropping down too low in gear? It should probably be around 750-850 in gear... if it is dropping down to 500 or less the motor will have a hard time staying running especially with headlights on, or a/c. the alternator when under load really can draw alot of power.
IF you do find out what the issue is please post your results up here too...
