Not real familiar with waverunners (this is a car and truck section after all), but remember that when you have been riding and stop engine it gets much hotter. Could possibly be coil "Heat Soak", or even a fuel system vapor lock issue caused by a pinhole leak in a line or a bad gas cap. Not very confident in this, but the best I got. Try posting in the waverunner section.

SOURCE: Intermittent Starting Problem

You have to determine if the problem is loss of fuel press or a los of ignition spark when the no start occurs, I suspect the fuel pump.

2000 Nissan Sentra 1.8 has hard start acting lot not firing and finally starts and immediately runs great. .

Check fuel pressure after it's been sitting for a while. It should be within 5-psi of spec. If not, you have a bad check valve in the fuel pump.

Runs good shut off for a few minutes restart runs terrible engine spits and sputters

A bad fuel pump may cause a 2001 Dodge Ram 1500 5.9l to run for a few minutes and just shut off without sputtering. It can also be that the fuel pressure regulator (on top of fuel pump assembly) is stopped up. Dodge Ram trucks have been named Motor Trend magazine's Truck of the Year three times.-----------------------------------------------------------------------------------------

My 2005 Silverado 4.3 starts and runs good. The check engine light stays on. It will continue to run good as long as I do not shut it off. When I shut it off for a few minutes and then restart it it...

If no evidence of anything wrong with the codes your being told to check. It might be your ECM is bad, I had a friend had similar problems and they put a new ECM in it and it ran great again.

My 1992 Jeep Cherokee Laredo seems to be going thru several PCM's in the last year or so. It runs ok then you shut it off and upon restarting at a later time it tries to run for a second or two and nevers...

When you change PCM are you disconnecting battery? (Hope so) If so, are you connecting negative cable last. If you are not disconnecting battery or not attaching neg cable last, you're hammering PCM with voltage spike and shortening life immensely
