In a 2002 Scag Cougar. Now it is starting up easily, running for 2 minutes, then shutting down. But then it will start up again, right away, but run less time, 20, 30 seconds, and shut down. It will continue to do so. I have a new fuel filter, a year old fuel pump, new plugs, and the fuel lines look OK. Year old seat safety switch, and other safeties bypassed (I think I have all of them?). To me, It seems like a fuel pump may be the problem, because the first time it starts, it runs longer than the next consecutive starts. I thought maybe a relay?, so I will order one of those tomorrow (memorial day weekend today). I bought this mower new, and it has been garaged.
