I have an early 1980's modle 318 Chrysler engine installed in a
mudboat. About 2 years ago I developed a problem with the Ignition
coil burning up. The engine has the original electronic ignition
system installed, but has been completely rewired by a Dodge
dealership, the control module, ballast resistor, and the distributor
pick-up assy. have been replaced. However, I continue to have the
problem. The engine runs perfectly for about 3 months and then without
any warning, will backfire and die. There will be no ignition fire
until the coil is replace, then the engine will start up and run fine
for another few months. Any help or suggestions with this problem would
be GREATLY appreciated.

Thanks
Ronnie
