Engine died on highway - won't re-start

[Peter Berrevoets]

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

Peter
