The car will start fine when cold. Run for about an hour or 2 then just die. Let it sit overnight and it will start right up. I have replaced the fuel filter and ignition control module. Still doing the same thing. While the car is warming up I did notice an exhaust leak coming from around the front doors. Could an O2 sensor or an EGR valve be causing this problem? I have only had this car for 3 days. I need it for work, but I am afraid to drive it for fear of breaking down. PLEASE HELP!

Try replacing the ignition coil. It sounds to me that when it runs for awhile the coil gets hot and then breaks down and is unable to keep enough spark going to run the car. Once it cools down its ok till it heats up

Could be ignition coil or a fuel pump going southbound

O2 sensor w/n do that/Try this disconnect the vacuum hose from the EGR and go for the ride.

Also try this when it dies immediately check for spark and fuel then comeback
