Hi Larry here. Is the unit giving you a fault code?
Customer: replied 1 year ago.
A code 3
Customer: replied 1 year ago.
Code 3 then 36
Expert:  Larry Welch replied 1 year ago.
This code indicates the unit is losing prime. If was service recently as you indicated, I would suspect that the fuel filter did not completely seal or the seal has failed and needs to be inspected/replaced. If this has helped you, please take the time to rate me so I will get credit for the time spent with you. If we need to go further, please contact me so we can do so. Happy Trails
