I have a 2001 115 Fitch which I purchased at the end of last season. The problem I have is that over 4K RPM the motor will run for a few minutes then shut down, sputtering to a stall most of the time. After a few attempts the motor will start back up and run fine under 4K. This motor only has 150 hours and just had the plugs changed, fuel filter...at the dealer fuel pressue is good no alarms or codes on engine. Took it out agian and bypassed fuel tank with portable tank. Ran at 5200 RPM for about two minutes then loss all power came to a stall and took about 5 minutes to restart. Again can run around 3,500 rpm no problem...no warning or alarms. Thinking fuel pump but dealer is telling me unlikley since it runs fine at mid range. Today they advised that the TPS sensor was being tied up by the throttle cable (wrapped up). They adjusted this and now it needs a water test to see if this was the fix. Do you think th eTPS would cause this type of problem? Thanks
