I?m new to this forum. I have a 1994 Yamaha 225 model S225TXRU 2S. When I start it, the eng react perfect. It goes into a little high RPM and after warm up it settle down and very stable. I start going and everything is ok. I run for a while and when I go in low RPM suddenly it turn off, (it turn off little by little you can tell is loosing prime). I have no problem in high speed. The problem get worse after we are running for a while and I go into low RPM speed. I change the three gas pumps on the side of the eng. I do an annual maintenance by schedule, so water pump, filters gas, spark plugs, thermostats are replaced.
Right now they are in good condition. Change lower unit oil every 6 month. Everything seems working fine but the low speed. Do you guys have any suggestion?

When you say "turn's off" do you mean it shuts off as if you cut the key? Or like its running out of fuel? May be an electronic issue...as the electronics warm up along with the engine warming up they may cut out.
