Chrysler Repair: Ignition Module, jerks, fifth avenue

Question
I have a 1983 fifth avenue and when I start it  it runs rough.  I got a full tune up on it.  It will run for about 15 minutes and just dies and will not start back for about an hour or more.  It also jerks when it is idling like it wants to just take off.  I was told to check the ignition module it is suppose to be on The firewall can't find anything that looks like this part. HELP!
