1999 Cadillac Seville STS Question: Why does my car stall??

My service engine light is on. i took the car to my local mechanic and he said that it was somekind of missfire code. My car stalls not all the time but today it stalled twice but it starts right up again and rides fine. The car has 84000 miles any ideas????? -
