This may not be your fix, but a place to start is having a technician check your EGR operation. (Exhaust Gas Recirculation Valve). The EGR helps the car reduce emissions by letting exhaust flow back into the intake to burn up unburned gas vapor while warming up your car. (When your engine is cold, it will not always burn up all of the gas that goes into the cylinders, so that gas just goes into the atmostsphere). When the engine warms up, it is unneccessary for the EGR to still be open. If it remains open, it can make your engine die, beacuse there is more exhast than air and fuel being burned. The reson this would happen would be if the EGR Valve stuck open (frequent issue).

The fact that you were able to repeatedly restart the engine after it shut down indicates that the battery was not totally dead and therefore the alternator is most likely to be OK. First thing I would do is take take it to have the diagnostic trouble codes read (Autozone used to do this sort of thing for free)

Key stuck in ignition


Be sure its all the way in park or try neutral.Its possible that security system does not recognize the key. Is security light flashing or on steady? Shut all doors and windows,trunk,hood, turn off all accessory's,roll down drivers window, turn key off and remove for at least 1 minute, insert key into ignition, try to start leaving key to run position for 20 minutes, turn key to off,wait 15 seconds, try to start again leaving key to run, wait 20 minutes, turn key off,wait 15 seconds, try to start, again leaving key to run, wait 20 minutes, turn key off, wait 15 seconds, try to start. This should relearn key code. It may relearn after 1 learn cycle and start if system is ok. Hope this helps and that the weather is dry and warm for this procedure! This is not always a fix, but works most of the time.
