Onan 7kw generator problem

My 2001 Onan cmm7000 efi is also putting out a 45 code... the rotor turns on mine while cranking. I checked the initial things that Rich Biebel recommended, and it ended with "best to have a pro look at it vs throwing money at it.".
Mine has 945 hours. Last time it ran was on a weekend when it was literally about 93 degrees, and I ran it all weekend with the AC on.

Keep us updated, as will I when I get a chance to get the trailer to the local repair shop. Mine is in the gooseneck....

btw... I believe Rich's phone is area code 973.... you may be able to run it up to him....
