Last week while using the genset (MEP 002a) it just shut down after running a few hours. It started back up and it ran fine for about 3 more hours. A couple days latter the same thing happened but twice this time. The Genset is now doing this more frequently to the point it will only run a a few minutes before shutting down. It always starts back up but I am finding that I have to keep the starter engaged until the genset reaches near full RPM or it will shut down while starting. I feel the problem is most likely with the fuel system but would like some advice before I start working on it. Fuel level in the tank is near full per the tank guage and with visual inspection. Thanks for any help.
