Spoke too soon!!
Went for a drive yesterday and after about 20 mins i started getting a misfire and the revs bogged down. I pulled over and checked all the connections and plugs etc but decided that it must be the coil again. First, I by-passed the ballast resistor but still had problems and the coil got quite hot which was not the case when the resistor was connected.
Luckily I still had the OEM 280ZX coil in the boot that I had borrowed off Huw so I pulled over again and swapped them over. Instant success as it ran sweet and did so for a good hour's drive after that. It seems that my dizzy has a particular taste for the original STC-30 coil and nothing else will do. I still have the ballast resistor connected up which has prevented the coil from getting hot and tried it again today where it started fine and ran for 10 mins without a hiccup.
It seems that I need to stick with the STC-30 coil but keep it ballasted.
