> No. As long as it has electrical power and the flight controls are working it can remain stable and glide even with a complete engine failure.

I'm not so sure about that. I'm pretty sure that flight controls are directly tied to thrust, because it would be the engine that also drives the hydraulic system.

It's like that even on passenger jets. If you lose both engines, you also lose hydraulics (aside from whatever little hydraulic pressure the ram air turbine provides). I would not expect there to be a ram air turbine on a fighter jet, which would mean complete engine failure = complete loss of hydraulics = complete loss of flight controls.

Nope. While it's true that the F-35 lacks a ram air turbine (RAT), it does have an auxiliary power unit (APU) that can power the flight controls, avionics, and electro-hydrostatic actuators as long as fuel remains. It also has a battery that can power critical systems for a few minutes when all else fails.
