As the no start issue is random, it usually occurs while out at the store or in a parking lot, never at home or a place where I can jack it up and get to the battery lead on the starter for a voltage drop test. I have checked accessible connections, finding no bad connections or swollen / corroded wires. Before investing time and money in a new starter, I will replace the starter relay and see if that has any effect. It has been over three weeks now without a no start. The saga continues.
