Looked at the video it tells us quite a lot
Unlikely to be loosing battery power the clock stays on
Its unlikely to be the earth strap, the body computer and ECU stay connected, no immobilizer light
My guess, and it is a guess, and can't think of a way to prove it with the tools we have
Is the crankshaft position sensor
It thinks the engine isn't running, engine check light is normally on without signal from the sensor
The oil and battery stay out because the engine still turning over
It would be pretty easy to confirm,without buying any parts, with a scanner that could data log, RPM would drop to zero as the engine check light came one
When the engine cranks but does not start, there would be no rpm signal
Here's a similar video
wink
I did notice that as the engine speed decreases the temperature gauge goes down
Looks like a thermostat is going to need replacing soon
