I have a 50hp (2010)Honda four stroke with very low hours which will start but never even reaches full idle speed before it quits. It is fuel injected and has fresh gas. Sometimes it will run until I accelerate and it kills immediately. Help. It must be a fuel problem but I am not a mechanic an I can't figure it out. Has anybody had this problem? Maybe fuel filter? I have never put any gas in it without also adding fuel stabilizer.
