Engine died on highway - won't re-start

[Jouko Haapanen]

My UrQ did the same to me once...had me stumped for quite a while.  My
problem was the pressed in vacuum hose fitting on the rear of the intake
manifold from which the ECU and some other vacuum lines initiate.  The
fitting seemed perfectly fine when viewed (trust me, I was poking around for
a while), but once I took hold of it, it just slid out of the manifold.

I pulled it out, cleaned it, and tapped it in with a rubber mallet.  Worked
like a charm, but only after being towed and spending an hour or so under
the hood scratching my head and going through various component tests.

I'd check and double check all vacuum fittings....

Have tried searching the archives but not having much luck...

While driving on the highway the other night, everything was going fine and
then the engine just died at ~120 kph. Total loss of power, costed off at
the next ramp and parked it. Nothing appeared to be amiss, pulled codes and
got 2221 - intake manifold hose failure to ecu(shouldn't kill engine), and
2214 - engine over rev (not this trip), cleared them, cranked the engine and
got the same codes again. Had it towed home :-(

Kind of stumped, fuel in tank, lots of battery juice, cranks over fine (new
battery), but just won't even hint at starting. Usually the code dump would
give a hint, but they don't seem to make sense. Hose to ecu checks out fine
but that shouldn't kill the engine, and over rev on starter cranking? go
figure.

Any ideas?

TIA
