Okay I've been having to use the old stang on a mail route some. yeah i know, anyhow after it's been run awhile it will quit and won't start back when it does it runs very rough for a few minutes but if you let it cool a few minutes it runs fine . It isn't running hot and it never does this with normal driving , only with a lot of shrt distance stop and go. any help would be great

when it won't start you need to check for lack of spark and or fuel

&lt\\;P&gt\\;got fuel &amp\\;amp\\;spark and have replaced the module on side of distributor thats why i’m sorta stumped&lt\\;/P&gt\\;
&lt\\;P&gt\\;&amp\\;nbsp\\;&lt\\;/P&gt\\;

Does your pump turn on with the key? What do your plugs look like? How old are the wires? Cap/rotor?

When you replaced the ignition module, did you put any greae on the backside? If you did, how much? Not enough or none at all will fry the module.

Was it running fine before the new module and coil?
