Well that sucks big time,i think you might be right ,it sounds like when you try to open the throttle it dies,but will run at idle,it sure sounds like a fuel pressure problem. ..and ya it should have been checked for sure,i hope you can get it serviced real soon in time for the walleye opener in a week.good luck,and the dealer had better make you a priority,because of this being a brand new engine and not even any hours on her yet....cheers
