After my first run-in with engine problems and subsequent searching the internet I bought a OVP relay. It never fixed any of the problems so it got moved to the bottom of my list of things to try, but it was still on my list. I just changed in and it starts and runs like new!

I'll take it apart and see how it looks, and re-flow it and probably put it back in, it's the one with 2 fuses and the internet says it a better one.
