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

If "nfg" mean the tap test didn't work, pour water on the module next time it stalls and see if it comes back quicker. If it did work, next time see if the pickup is shorting when hot enough to the distributor body.

Loaded stumble (in gear, stall the converter) is typically weak ignition to the plugs but I thought it was only part throttle that this happens. Ohm the plug wires also.
