2004 Yammie F115TXRC<br />OK...Where to begin?<br />Out boating w/ the missus yesterday, started out fine, smooth start, everything normal. Ran up the river for about 45 minutes@4000 RPM, saw something interesting, went to throttle back to stop and look and the motor dies. I try to restart, the motor turns over fine but won't catch. After about five minutes, she finally starts again. I decide we're far enough from home and turn around. Coming back down the river, she sounds ok at all power bands, but at WOT she's missing sporadically. OK, it's 9:45am and we're not ready to go home. We stop at an island near the launch to hang out for awhile and I go to turn her off, now she won't STOP running! I open the cowling and disconnect a relay, she dies out. I reconnect. We have friends w/ a boat there and decide we can always tow her to the nearby ramp, so we hang out. After a few hours of hanging out, she starts fine and stops fine when I turn off the key, I do this a couple of times to make sure. We head back to the ramp to load up, as I'm coming in she dies at low throttle. Ten minutes later, I finally get her started again. Thankfully I get her on the trailer.<br />Is this a heat related problem? ECM? Pulser Coil? Any help will be appreciated.<br />
