Default quick question.....

Lately when I start my car it will fire right but then die. When I fire it back up it will start without hesitation and run fine. Also my RPM's seem to be drop very slowly when revved in nuetral what could it be?

Check this article out, it is for rough idle but you can try to increase your base idle to get it to run and then follow the article and tweak from there to get a steady idle, also cheack all your connections and clean rotor button contacts, is your fuel pump priming correctly?

Check your throttle linkage for binding or not returning closed. If that is ok try cleaning your Idle air control valve (they get carboned up). You may need a new motor on the valve.
