WHAT IS THE CAUSE OF THE PROBLEM AS DESCRIBED BELOW on 2005 Chrysler Crossfire

AFTER DRIVING CROSSFIRE FOR ABOUT 5 MILES, I PARKED AND SHUT OFF THE VEHICLE TO SHOP. ATTEMPTED TO START VEHICLE THAT TURNS OVER BUT WON'T START. ENGIN CONTINUES TO TURN OVER FOR SEVERAL SECONDS AFTER IGNITION KEY IS RELEASED. WAITED 1/2 HOUR THEN VEHICLE STARTED, AFTER DRIVING 5 MILES VEHICLE STOPPED RUNNING WHILE DRIVING. ENGIN LIGHT WAS ON. THIS CONDITION REPEATED WITHIN 24 HOURS. VEHICLE RAN VERY GOOD PRIOR TO THIS CONDITION. NO PRIOR PROBLEMS
