Distributor blues..

Okay, so I finally got my replacement (Accel) vacuum advance mag pickup distributor. It's a Mopar replacement. I'm having problems again. It starts fine when cold. It idles/runs better than the old distributor. Every time I shut it off when its warm it doesn't want to restart. The reluctor gap is good. Battery voltages, starter, are okay. It cranks good.

The car starts fine with the old distributor when its warm.

I hate the thought of getting a new distributor again. It's an MSD system that runs with the old distributor .
