It is true that this happened to BA on 24 Jun 1982. The 747-236B G-BDXH flew through the plume of a volcano eruption.
It takes quite a bit of ash and smoke to actually shut down the engines, so this plane was at once supremely unlucky, and then supremely lucky to recover. The plane was a glider from FL370 down to FL130 and still only got 3 engines to stay lit.

Most active and semi active volcanoes are in a ring along the coasts around the Pacific Ocean and islands within that ring (including Hawaii). Better detecting is being developed on site and from satellite sources to locate and indetify possible active volcano sites so the risk of the 2 noted events is probably reduced in the future, although not completely negated. Flights can then be re-routed to detour the high risk areas.
