1992 90hsp mariner outboard 3 cylinder 2 stroke<br /><br />I have been experiencing some odd issues with this motor. I live on a lake and have been using this motor all summer. My problem has only occurred one time prior to this time. I will try to keep it short and to the point.<br />1. THURSDAY--Motor running fine<br />2. FRIDAY-- Motor cranks fine no spark<br />3. SATURDAY--- Motor starts and runs for 15 minutes, then I shut it off. Restarts immediately. 4 hours later, motor does not start, no spark again.<br /><br />The last time I had a spark issue was 4 months ago and the motor restarted 30 minutes later. It has never died when in use and had been very reliable. Plugs are clean and fuel is flowing fine. Does anyone have any idea why this situation would occur? I am running out of boating time and would appreciate any suggestions.<br /><br />Thanks,<br /><br />Mike
