while fishing this past weekend, the motor started great at the landing and I drove about 1/2 mile to my fishing spot. turned the motor off with the key. 30 minutes later the motor turns over and it gets gas but wont fire, no spark in any of the 4 plugs. Anyone willing to share some insight as what to look for? I checked all the wires and looked for loose nuts ect. What should I check next? model number is 115 ELPTO sn 06348560 THANKS FOR ANY REPLIES
