I have a 1999 yamaha
You must try to crank it by hand ,remove spark plugs so there will be little compression and then try to turn the motor it should turn without to much force this will indicate the motor has not seized when hooking up a jump start do not connect both leads directly to the battery ! the red + lead should connect to the red+ on both batteries but the neg lead - should not go to the battery post but to a ground usually directly to the metal engine cover or you can damage the battery !

does this happen repeatedly or just sometimes? check the one way vale and the line its attached too on top of the fuel tank then make sure theres no water in the fuel filter, if there is water in the filter it should be visible and kind of look like a bottle of salad dressing or oil and vinegar before its been shaking up.
My 2004 yamaha jet ski fx 1100 wont start
sounds like either your fuel pump has gone out or engine has possibly skipped some teeth on the timing chain. make sure u have fuel pressure going into throttle body assy or if you have good hearing, you should be able to hear the fuel pump running for about 5 sec if u just tap the starter. also need to make sure youve got no water in the tank, so the easiest thing for u to check on your own would be to cut off the hose clamp at fuel rail and put the hose into a clear glass jar and tap starter. if it fills up then its probably not a pump, but if the fuel looks cloudy then you got water on there.
