ok so i changed the distributor. My vacuum advance was shot, and after tinkering with the timing and the carb a bit the truck stays cool.. so i'm going to ventrue to say that my timing was too advanced and the carb was set too rich.. thats why i was overheating.. but... after about 30 min of driving she did the same thing.. sputtered on acceleration poped through the carb and eventually just quit on me at a red light. I pulled the wire that goes from the coil to the distrib and turned the engine over.. NO SPARK!! and after about 20 min i turn the key and it fires up with out even one full turn. I have been though about 10 ignition modules and it does the same to all of them if it's even the igniton modlue thats giving out... The only thing i can think of is that i put an accel coil on it, and i'm running a stock ignition module. Could that coil possibly be pulling too much juice and overheating something? Is it the even the ignition module at all, becuase i have tried changing out the hot one for a cool one and i still had to wait 20 before it would start. Whats my next move??

 

Based on this and your other post, I'd say a component is getting hot and is quiting until it cools down. You've got another distributor in the engine and based on your posts, it runs good for a period of time. You've also tried changing your ignition module while the problem is occuring with no positive solution until time has passed.

I personally would try replacing the coil while it won't start and see if it fires up immediately then. If it does, your coil either opens or shorts when it gets hot.

Is a ballast resistor wired in to reduce the voltage to the primary windings of the coil?
