iamalienru,
I was just wondering, I don't know if you know anything about the "Codes" that, that gen can throw out if, and when it has operational issues. If you're not familiar with them, the codes show up as a sequence of blinking of the LED light, in the on/off/start switch of the gen itself.
When your generator shuts off on its own, is that switch "blinking" in any form of sequence? That is, something like three flashes, a short pause and then three flashes more, then a long pause, and the sequence starts again?
