When it's not starting you have to determine if its a fuel or an ignition problem. The ignition is easy just see if the coil and plugs are firing or not. If so, maybe its fuel related.. Is there an electric fuel pump and is it working and filling the carb bowl??? I have had Onans with bad elec fuel pumps and ALSO check any in line fuel filter. If it has an elec fuel pump insure its getting power and often you can hear to tell if they are running or not.

If its an elec problem (no spark) I have had a bad coil or condensor go bad once warmed up
