help, car dies abruptly then starts right up

[kmbonomo]

Ok, I have a new problem developing, was sitting at a stop light car idleing perfectly then it died, I started it right back up it ran fine the rest of the day... The next day I was cruising down the road car running perfectly, then just died, I glided to the side and restarted right away and it ran perfectly the rest of the day.. yesterday another instance.. Now the car is doing it alot, several times in a row But the car is running perfectly before and after instances when cold with no sputtering of any kind. any ideas?? Keith
