My 351 engines stops running about 2-3 minutes after I initially start it. I'm a mechanic and this has me stumped! It is in the ignition. 12 volts is fine on the coil: I just simply lose spark. New cap, new rotor, 2 different coils, and the problem now is so bad I can't use the boat. The distibutor is a Prestolite, screw down cap, electronic. I do not knowif this is a conversion from points prior to me purchasing the boat. I'm convinced the problem is in the electronic module within the distributor. Should I replace just the module? Has anyone used one from "Hot Spark"? ($69.00) or should I go with a Petronix. If so, I would like to use the coil I just bought from Napa (internal resistor) Thanks for the help!
