Onan Genset won't stay running fixed

I have a 2000 onan 5000 genset in my Suncruiser and I have had the problem many people have had. It will start when you push start but will shut off when you let go. Many people had some answers but Flightsystems.com had the parts. Replaced the voltage reg and the board and wow it started right up and keeps running works great and there parts are made better that the oe ones. Thanks Flight Systems.
