I think you're misinterpreting reports of stall-related incidents as being an engine stall, but the most common accidents are related to 'aerodynamic stall'. Engine stalls are virtually unheard-of.
“And by far the most common reason piston engines quit is because they don’t receive fuel, either due to fuel starvation (the airplane has fuel but it doesn’t make it to the engine) or fuel exhaustion (the airplane truly ran out of it). These two causes account for over one-third of engine failure accidents”
