Sorry, off the OPs topic, but I wouldn’t un-recommend Stabil or any of the other gas stabilizers.
Another suggestion that works well for stabilizing or using small amounts of fuel in engines without catalyst emissions and 02 sensors is 100LL. It’s not much more $ than non ethanol premium and it does not need to be treated or drained for about 2 years.
It’s more highly refined than automobile fuel.
OP issue sounds like a voltage or sensor issue. I do not have any direct experience w Onanistic but the suggestions sound right.
