Guys, 
 Not sure who posted that the sensor in front of the intake manifold is a
boost sensor, pretty sure it WASN'T Glenn though.  That particular sensor
is air temp and is capable of shutting down fuel AND OR igniton at ~4000
RPM.  Don't know if you got my last messages Paul but 2 other things can
cause the shutdown as well (besides overboost) faulty coolant temp reading
from coolant sensor and or bad idle switch function.  Since my fuel pump is
hard wired , I'm leaning toward the air temp sensor as mine feels more like
ignition loss anyway.  Got home real late last night paul so I forgot to
get the Ohm readings to test the various sensors (pretty sure air sensor is
18 + 19 on the ECU though), will remmber for tomorrow, in the mean time you
can check your connections to these sensors for continuity etc.  Check you
tomorrow.
