2001 Chevy Silverado V8 Four Wheel Drive Automatic 170000 miles

Service engine light on. Code oxygen sensor. Tried BG44K gas additive, Ran well for 2 days then died and wouldn"t start. Can bad oxygen sensors cause an engine to suddenly stop and not restart? Truck has 4 o2 sensors.

No, but a clogged catalytic converter can and a faulty cat. Converter will often throw the oxygen sensor trouble code as well.
