351 Windsor starts and runs great.
When hot it will not start. Acts like there is no spark.
Have replaced points, condenser, coil and external coil resistor.
Spark plugs, plug wires rotor cap and rotor button have less than 40hrs on them.
Any ideas? or just wail 15 min between ski runs.

Have you put a spark tester on it? Have you looked in the carb to see if it is flooding when you shut it off?

check/clean your battery connections and ground to the engine. if your battery cables are original they might be ready for replacing. if they crackle and pop when you bend the cables they are corroded under the plastic.

another forum i read, people complain that heat forces them to pump the throttle when hot.
