I have a 1976 302 Ford engine in a boat that stalls after running about 45min. The engine will restart after a few minutes and run fine for about 10min. and stall again. It has an electric fuel pump and and a Mallory distrubutor with points. I have been told it might be the coil which is mounted on the intake manifold but haven't had time to check that out. Sometimes the engine will not stall and run fine. Help! please

a few things may be the problem but it sounds like you should check the coil. you said it doesn't have that problem on some occasion's, was there a diff. in the outside temp.? and is the engine in a closed in compartment? could be heat build up. and by that mean if it is closed in, the compartment may be building up heat and causing over heating of the coil or even your fuel delivery system. might look at those things and also do have a temp gauge on the motor, is it running at normal temp? need a little more info....

Duraspark boxes and dist pick-ups were notorious for this in 4 wheelers.

my guess would be because it's in a boat there is added moisture, try replacing your points with a thing called the "ignitor" from pertronics, and replace the dissy cap that would probably help you out some or use some duct tape and wrap everything with it spark plug boots dissy cap coil and all that good stuff
