1990 E150 Econoline: Alternator or voltage regulator issue

I'm having a charging problem.

Alternator with new voltage controller was replaced in April 2020. Battery was charging at 14v when engine was firing. No problems until last weekend.

Last weekend, while driving, I noticed that the voltage was below 12 (from a meter on a usb adapter in 12v receptacle). Uh-oh. Van eventually stalled; not enough juice to fire spark plugs. I jump with a house battery bank and got home. Charged up everything, starting battery is good (all batteries good)...
