I have a 1971 29' Ericson sailboat with automic A4 motor. Runs great, sounds great; but after about an hour of running time it stalls. So far, it does restart but only after it sits for a while. Any thoughts?
Do you have the electric fuel pump?

+1 on the coil. I had the exact challenge you discribe.New coil, no stalls, 2 1/2 years now. Do you have the Moyer A-4 Bible?
A coil overheating or having some other failure with run time is definitely possible. There are cheaper ways to test for spark...., but having a spare coil on hand is good regardless. Something else that could be going on is a clogged vent line on the fuel tank. So, if this happens again, loosen the gas tank fill cap, and see if it starts back up.
There are other things, but I'd put both of these high on the list of first checks
The reason I asked this is because there is an electrical connection from the pump to a sensor on the engine, and when the sensor is bad or the connection corroded you get the kind of stalling you describe. This cost me a $100 visit from the mechanic to find out, but I'll pass it on for free. I tried the coil replacement first, but that didn't do it. So try this if the coil doesn't work.
