Since having the car towed home I have checked all connections in the ignition system, pulled the distributor base plate out and cleaned it--the the two pieces were very tight. I have let her run in the garage for long periods of time and she has not shut down again so I haven't been able to check spark. 

When it did shut down, it wouldn't take long before she would start again then shut down. Then start, then shut down. 

I know my trial and error method wasn't the best approach, but without being able to check spark it seemed appropriate to change out components. 

Tell me if my analysis is correct on this. I thought it might be a fuel supply issue. So---I pulled the float bowl covers and all was ok there--also pulled and cleaned the carbs. If the float bowl jets were stuck in a closed position it would get no gas and eventually shut down---but---both would have to stick so each carb wouldn't get gas. this seems like an unlikely condition. 

If they were stock in the open position it would be dumping gas out of the overflow tubes---so, again, unlikely since it would still run. I have already changed fuel filter and blew out the line. The pump pumps normally and each time I pulled the float bowl caps, they have been full of gas. So--I have basically ruled out fuel starvation as a cause. 
in the garage she sits and purrs forever with no shutdown------so, as I mentioned, I can't ch spark
