Check the oil level and keep your gasoline tank topped off. We discovered that our gen will simply quit if the oil level or fuel level drops. Good luck.

my 2016 FR3 30DS does the same thing, Saw that the 2017 model now has a vent with a boot inside to let air into the generator. FR probably made the change due to over heating. I will be installing a vent in my Gen door.
