87 mercruiser 350 magnum
engine cuts off at full throttle, sometimes it will shoot right back on at full throttle. When it does ut off it takes about an hour for it to start back up. Enfines has not cut off at half throttle yet. When it has cut off some times the engine is completley dead, the fuses pop on the circuit breaker. Mostly it just does not turn over until it cools down. Any suggestions?

Hmmm,

First, as no help - A friend of mine with British Cars offered "Perhaps, like my car, the engine needs to contemplate its sins before restarting".

Intermittent "heat” electrical malfunctions can be hard to run down. Two things though – Poor grounds in the wiring and ignition components are the likely source.

It does not seem to be just one thing since you have an engine that stops (sometimes) when hot and then starts when cold yet it also pops breakers….
