Guys, my motor starts fine when i first get to lake, then after its warm I have a hard time getting it started again. It smokes alot and runs rough at idle. Today it started completely stalling a wot, would crank back up and run fine for awhile then do the same thing. Any suggestions? O2 sensor VST Screen?

Check fuel filters, water in gas,spark plugs, fuel pump diaphragms(low pressure pumps). Check fuel pressure at VST and check for fuel restrictions in fuel lines.
