The las three times I have filled up, immediately after words the car stutters, misses and dies for the first mile or two. Is removing the gas cap to fill up the gas tank causing a loss of vaccuum or something that then corrects itself as I put a mile or two on the car?

You may have a fuel pump starting to fail. You would have to monitor the fuel pressure with a gauge during this period to find out for sure.

Fuel pump? I thought thechrysler 300c has a fuel injector, not a pump?

Yes, it has both. The injector times the squirt into the cylinder but the fuel pump maintains pressure to the injector.

Great. Thanks for the fast resonse. I am going to take it to the Chrysler dealer and have him replace it, unless you think an independent can do the job as well for less money?

Nobody suggested to simply replace the fuel pump. My advice was to test the fuel pressure during the failure to find out if that is the problem or not.
