So you say your ignition tune-up stuff is all in order.  And you have looked 
at a number of other things.  Your head temp sensor resistances are OK.  But 
you didn't have "tested and cleaned the trigger contacts" on your list.  Try 
that.

To test: Unplug the condensor from the coil.  Unplug the 3-prong connector 
to the trigger points.  Have an analog VOM?  (Could use digital, but I think 
analog is better suited here)  Hold one lead to the center pin (this is the 
common pin) and hold the other to one of the outer pins.  Switch to measure 
resistance.  Have somebody crank the engine as if to start the car.  The 
needle should swing back and forth between zero and infinity as the trigger 
contacts open and close.  Repeat this on the other outer pin.

Still good?  Well, the contacts could be dirty or intermittent.  So pull the 
trigger contacts out of the dizzy and clean the little contact points.  Drag 
a dollar bill through them.  No filing.  The little room where the points 
live should be reasonably clean.  If the points get oil or crud-fouled, they 
may work intermittently.  It is also remotely possible that the points are 
going out, so if you have another set to try...

I guess it could also be intermittent spark plug wires or connections or 
sticky injector.  But I'm betting on the trigger contacts.
