We dove it again last weekend. It took about 15min of drive time before it died. After that, it started dying at a faster rate. Noticed something this time though - the blower motor was on, and when the engine died, ALL power was lost, so its not a localized power loss at the HEI. As always, while still coasting, put it in N and she fires right back up.
There shouldn't be much between the battery and ignition switch, but that car has small electrical modules all over the place, I'm not sure what most of them do, how they're routed, or if they're even from the factory build.
