UPDATE
Went to the garage this morning. She started right up.
Proceeded to clean and re-connect battery terminals and connectors. They looked good, but pulled, cleaned and re-tightened.
Went underneath to check the ground. Bolt was rusty, and some rust on the connection. Disconnected, wire brushed frame, connection, & secured with new bolt. Started right up.
Getting some rain, so test drive on hold.
