I have an 86 Supra T6m. It has the 351 Pleasurecraft engine. It was stalling at low RPM's when it warmed up (vapor lock or something), so I ran some carbeurator cleaner through it. Now that issue is gone, but after about 30 seconds of running at 3000 RPM or so (when skiing), the boat completely cuts out on me. It seems to surge a bit before stalling. It's like it is starving for fuel. It does this on a full or a half tank. It only does it at higher RPM's. No problems at low RPM's.

Has anyone had this happen to them, or does anyone know what would be the first place for me to look/start replacing?

I have had the boat 2 seasons. I have not rebuilt the carb or replaced anything yet. Spark plugs are fine. All belts and hoses are fine. Would it be a fuel filter or just an old carb? Maybe a bad fuel pump?

Thanks for the help!!
