Elec woes, crank, no start after running then parked.

I had a conversion Mopar electronic do similar stuff. Started good cold. Drove it out to get gas and would not restart. After getting the car towed back home I found that the gap, which I didn't check for myself before installing the new to me distrbutor, was set too wide between the reluctor and the pick up coil. Set the gap to 0.008" and everything's been fine since.
