I have started having trouble with my mower. Friday when mowing I cut the mower off to get a drink. Upon refiring it ran good for about a minute or so and then died. Like it was getting no fuel. Changed fuel filter, still nothing. Talked to my dealer, he said to give the fuel pump a little drink of gasoline to get it primed. Did that andd fired right up. Ran the rest of the day. Saturday only time shutting mower off was to move from one job to the next. Today after church went out to mow my personal yard, mowed about 45 mins, shut it off to move trailer from behind shop. When I refired the mower it again ran for a minute or so and shut down like it was starving for fuel. Took line off after fuel filter and squirted some fresh fuel in line and ran another hour or so. I am running ethanol-FREE gas. 93 octane, gas tank has been anywhere from half tank to nearly full when it has done this.
