Jmark Cool! Glad you found the problem, although the "fix" is a little time consuming. If you need some help on removing the pickup, let us know.

Jmark If you find a problem in the dist and it's got a lot of miles, you might consider buying a new one.
I've bought two of these from this seller and have been more than happy! Both are now over 2 years old and doing great. I know it's not an MSD but then again, it doesn't cost 200 bucks either! LOL

T-bucket23 Sounds like a module as generally the pickup will not be effected by heat as quickly. You can take the module to be tested, if you do make sure they heat it up good by testing it several times. If you do replace it make sure you put the grease on the new module and be sure it is tight.
Please dont buy an Autozone or other replacement piece of crap. Look for someone who stocks Delco and get the right one. The OEM modules are far superior to most of the aftermarket ones.

justold unplug the pickup leads and connect an ohm meter to the pickup then gently pull on the wires and watch the meter to see if you loose the circuit ,if so replace the pickup .

Jmark The secondary circuit is probably taking a crap. Could be the module or pickup. Try unplugging the vac advance and see if it runs better. Sometimes the wires on the pickup will break inside from the constant moving from the advance. If it runs better, you'll need to pull the dist and replace the pickup. If not, you may have a bad module.

techinspector1 Clean and re-attach all ground wires, body to frame, body to motor. Sand 'em down to bare metal, then gob RTV on the front and back sides to prevent oxidation of the connections.
