your plan sounds good.

your testing does not say the temp sensor is bad..
but ...
it's easy to try, and not a terribly expensive part..
so it's worth trying.

next time it does it..
check for  ignition right away...
the most common reason I have seen for a no-start is lack of ignition...
as long as it's not a fuel supply issue ..
and I have seen this ..
( it was on a 2.1 though )
start cold fine, run mostly ok, ...it would rev up by itself ( not something
that happens to 1.9's ) ...
shut it off, then wouldn't re-start..
that was due to being too rich and flooding ..

don't be tricked by flooding is all I am saying.

let us know.

84 Westy 1.9L Digijet

(for the benefit of the "digesters", I deleted the string, but it is a very
good string...)

So, she started up again cold, I drove her until the coolant needle reached
normal hot (needle just left of the light (light is off). Got back, shut
off, would not restart. Then I started zeroing in on the Temp II sensor.

Got zero ohms from ground terminal at connector to engine. Check. Got
correct ohms at Temp II sensor (per Bentley 24.32) and at ECU connector (per
Bentley 24.20) terminals 2 & 7.

When the engine cooled just a bit (maybe 15 minutes), it started right up.

I'm still going Replace the Temp II sensor, but of any additional ideas,
thank you.
