And yet many people use turning over to describe a no start, but engine is still cranking situation. Makes no sense to me.

Hi, currently sitting behind a safety barrier on a 60mph road waiting for AA.
Disco 2 V8 2004 60k miles.
Turned engine off whilst parked about 30 mins back, wouldn’t turn over when trying to start it back up. UG was showing voltage dipping from 12v down to 11v when trying to start, someone helped jump start and we left it running for 15 mins seemed fine and UG was showing 13v and healthy everything. No codes.
Driving home, after 20 mins on a 60mph hill the engine just cut out. Ultraguage first showed a symptom of engine temp ERR after the engine died, then screen went blank and obviously power steering and brakes went out.
Coasted to a safe location and pulled handbrake at 2-3 mph to stop the car.
Windows, lights, radio works but car tries and fails to start.
Crank pos sensor maybe? Alternator issue?
Extremely unnerving to be doing 60 down a steep Scottish hill towards a roundabout and everything to fail haha. Luckily no traffic today because everyone is away for the holiday!

Think of it this way. The crankshaft is turning over, which means the pistons are moving up and down, but the truck won't fire. The starter makes the engine turnover, combustion makes it run. Not turning over is what happens when your battery is completely flat.

I was thinking about something like this - assumed the heat from the exhaust (that me and AA guy both burnt our hands on 
) eventually kills the sensor like heat does to all electrical components. Must be some sort of heat shielding or insulation fix to extend the life a bit.
Appreciate the education on 'turning over' as well. Help me correctly diagnose in the future.
Out if interest, any reason jump cables connected to another battery worked to start the engine? Or was it just coincidence that by the time we hooked up the cables everything had cooled just enough?
