Well, I was insulting the Yanmar starter button without enough data.... it turned out that one of the starter solenoid wire spade clips was 99% off of the solenoid metal spade, only held on by the plastic sheath, maybe making metal to metal contact once in a while. Hard to see but easy to detect tracing voltage drop. Crimping it a little so it takes a firm "bite" and attaching it again, solved the starting issue.
