I got my mfs40a 4 stroke 1.5 years ago and topped out at 36mph. Since then I have notice power loss and only get 30mph now. Brand new fuel lines , filters , spark plugs, oil. Still same thing. Was told my injectors we’re probably getting dirty and to add injector cleaner. So after I did that went to the river and my power was back for about a 100 ft them motor started cutting out then back on. So I killed motor. Usually when I click key to on position I hear beep and fuel pump run then beep goes off and turn key motor starts right up. Now I click key to on and no beep and fuel pump doesn’t come on. Any ideas?
