Engine died down at high RPM.

I finally got to take the boat out for a good run today after a pretty bad week weather wise, and it looks as if it was either bad fuel, or the wires.
I looked at the old wires with my ohm meter and one of them was so corroded it wouldnt show me a short from one end to the other.
I still have to take a look at the plugs to see how they look, but the weather turned sour again so I'll give it a try later on this week.
The fishing has been getting good around here so I'm glad I'm back up and running.
Thanks to all for the help, I'll look further into the suggestions if the problem shows up again.
