Ken, The first thing I would check is the pulse coil. 600ohms about cold and hot would be open. And 2nd would be any loose connections on the resistor. If ok then back track from there.

Here is a problem I have had on two cars. The car starts normally and runs fine. All of a sudden it quits Diagnosis : No spark. There is power to the coil and when you put power to the key you can get a spark (one) across a plug when going direct from the coil)
