Stalls at temperature, only when coming to a stop.

You cannot get correct actual data when it is suffering from running off the battery, these cars are very sensitive to voltage changes, particularly low voltage. Get a new regulator and then look again.

Will do, thanks JFP, I'll report back when it's replaced. How did you determine its the regulator vs alternator, ground straps or battery? Not questioning your expertise, I'm just curious how to diagnose these myself.

Simple: We test everything, voltage drop on the cables, load test the battery, and run a diode test on the alternator; all easy to do with the right tools. Plus the voltage regulators in these cars are a common failure point, but we still check.
