A loose connection would be one thing to look for. Also look for dirty slip rings, sticky brushes in their holders, etc. While we see people cleaning slip rings with emery paper it isn't suggeated, there is a cleaning stone available from electrical supply houses that looks like a big abrasive eraser that should be used.

Beyond that you are probably looking for a generator repair shop to get deeper into the unit.
