Warren,
It seems like you have touched upon just about all the common causes. Have you checked or replaced the hall sensor in the distributor yet? I had a problem with mine a while ago and it drove me crazy because it was intermittent. These tend to break. I would suggest swapping the whole distributor if you have the option. Be careful not to put any stress on the hall sender and wiring if you replace it.
Best of luck!
