Stalling

[Blaster Berg]

I have a mercruiser 3.0 l that has been running excellent for about 7 years. The last couple of trips it has started to stall after I've ran it for about half and hour. It's stalling at high rpm and almost feels like it's not getting fuel. It runs excellent before about the same time period everytime, so I'm thinking it might be an electrical problem. What do you think?

Re: Stalling

What's it doing? Is it gradually losing power, or just suddenly losing all power and dying?

What RPM?

Will the engine restart after the stall?

How's your temp?

Fuel Injection or carb?
