Have a 77 Pace Arrow rv with a dodge 440 engine and dodge electronics. I have replaced Ignition module, distributor, starter relay, ballast resistor, ignition coil, ignition switch, when the vehicle is cold it will start right up and run for 45 min to an hour then dies like someone turned the key off and then it won't restart it seems to have lost power on the negative side of the coil very dim on the test light an no pulse to coil HELP PLEASE

 

Does it have athe leab burn system ? If so you should convert it to a non lean burn.

 

check your fusible links out real good, i had a similar problem when one burnt up.

 

actually both fusible links on the starter relay were changed when i changed the relay and as far as the lean burn system i don't believe it has it because it is a 77 pace arrow RV
