I have a 2001 Seaswirl bowrider with a 4.3 V6 Volvo and an SX outdrive. I have been experiencing a problem recently whereby the engine, only occasionally, will all of a sudden "die" when the boat is getting up to WOT. When I try to restart the engine it turns over but does not fire. It is only after I have let the engine "rest" for a minute or two that it will fire up again as if there was never any problem. During a full day of boating this may occur only once or twice! Does anyone out there have any possible idea of what could be going on here? Thanks.
