Nissan Repair: 94 Altima Stalls while driving, air meter, altima

Question
The car will start fine, and then 20 minutes into driving start stalling. It will be hard to start, but once it starts will run again for a short while and then stall. It seems not to stall at idle/park, but only while driving. The distributor has been changed recently (it was leaking oil and had to go!) along with new wires and the problem disappeared. What should be checked next?
Thanks!

Answer
Stephen,

Check the new distributor to see if it is leaking oil since it is a rebuilt unit.  I have seen them leak when rebuilt.  If this is not the problem check the air meter.  You did not mention if you were getting a MIL light?  If so what is the code?
