Is your oven on a dedicated circuit? It could be tripping if you have a hood vent or something of the likes on the same breaker

I did just redo 20 amp service 12/2 see if that solve issue.  I did notice main feed ti condo unit had 100 amp master breaker in crooked?  Possible issue we never tested original oven 220 before bought dumpy place.  Some say door switches go bad on these.  Complete shut downs quite quickly.  Breakers never trip only oven.

I may head over condo yank this out so work on it home.  Inspect power wires on back feed see burnt.  Any burnt wires around door switches maybe test those volt meter.

Ok found thermo cutoff burnt wire replaced now works.  Once pulled out obvious what cooked.  Now wondering why failed maybe pros chime in
