That's what I'm thinking, diff warms up, switch warms up and things expand just enough to where a short becomes a contact, maybe because of a dirty contact in the switch. Wouldn't make sense with the wiring as I can' see that getting warm enough to be subject to thermal expansion. Maybe if it's really close to the switch or even in the connector to the switch, I'll make sure to spray that too.
