It could have shut down from an electrical malfunction, but it could have been an ECU gremlin due to the rebuild. Mine just flat quit on me once during a break in run on coast down, but it re-started immediately and never did it again. I wouldn't worry about it happening once.

The coil arcing is a problem - could be a bad coil. Remove the connector and test the primary side (the 2-prong blade terminals). Resistance measured across the terminals should be .72-.88 ohms. Now measure resistance between the (+) side of the primary (that's the vertical blade) to the high voltage secondary terminal (where the coil wire goes). The standard value is 10.3k-13.9k ohms.

Check the resistance of the coil wire (end-to-end) and the spark plug wires:

coil = 3k ohms
#1 = 9k ohms
#2 = 8.5k ohms
#3 = 10k ohms
#4 - 9k ohms
#5 = 12k ohms
#6 = 10k ohms

Those are approximate readings for the wires - within 5-10% should be fine.
