1993 Chevy Blazer engine stalling
engine stalls for no reason. either while driving or idling at a lite.just like shut off key but restarts with no problem.does not throw a trouble code.have run with fuel pressure gauge and holds steady psi.watched spark with led monitor but stalls with spark still fully available.may stall several times in 1 mile or may run for 1 week without a hint of trouble.replaced complete exhaust system 1 month ago over plugged catalytic convertor.i am a hd.mechanic but this has me stumped.is this vehicle just sticking out it's tounge and saying you know nothing?

sounds like an ingition module to me. i think i would install a reman distrubitor with new pick up coil and module. i had one do that before and guessed at that and it worked for me. this is a hard one to figure out

EGR could be sticking, vaccum leak, is this carberated or fuel injected
