I have a HondaEU3000is generator mounted behind my semi to power my air conditioner,
It dies every time I negotiate a on or off ramp curve also on windy roads. What can I do to keep it running, on straight roads it does not die and runs fine

Try a weighted fuel pickup attached to a line flexible enough to move to the side the gas is moving to.
Peace,

This sounds like the problem NASCAR drivers have when their at the end of a long green flag run...

Your fuel is sloshing in the tank, and having a hard time being picked-up when you make those turns. The generator engine is being fuel starved. (Think centrifugal force)

What you need is a tank with baffles in it to help control the sloshing, or some type of leveling system there on the Tractor aft/service deck to keep the generator level.

Just a thought, could the generator engine be converted to propane or natural gas... what's your refer run on?

Darn it Clarke, you bet me agin'... k

There is a slight possibility that it's the oil level switch.

See if it does it with a full tank?

Hi,
I agree it could be oil level, but doubtful. I do know that those service trucks or trailer that John Deere dealers did their Ready To Mow at home servicing had Onan generators powering the equipment and were very sensitive to inclination for the fuel pickup (which was rigid) and unforgiving when fuel was not being picked up (pumps were cooled by the pumped gas.)
