'74 Gremmie woes

["Jon Eisen" <fuldamobil@xxxx>]

So, I'm a pretty amateur mechanic and am learning a lot working on my Gremlin. I replaced 
my distributor with a rebuilt one 6 months ago after the car started running very rough, 
and it made things much better. Now, though, the car will run rough like it was before and 
then die after a couple miles of driving or like 7 minutes idling. After sitting for a while, 
it'll start again. The motor doesn't seem to be overheating. Any suggestions as to where to 
look? Thanks.
