Chevrolet Repair: corvette fuel delivery 1995 lt-1, intake plenum, vacuum line

Question
vette starts runs ok; until about( 2+ -) miles acts as if no fule avaible; engine will slowly die out. problem more extrem if stops or slow for corning is in volved. fuel pressure seems to be ok at check port on fuel. also can cycle switch to off on and instantly the car will restart with same problem as above

Answer
sounds like you have a faulty EGR valve.  It is located under the intake plenum.  First check the vacuum line going to the EGR valve.  If okay, disconnect the EGR and see if it still stalls out.  Also Is there a check engine light on?   if so have it scanned for a DTC trouble code.  That will give me more info to work with
