My 93 blazer runs fine until it gets warms up then it stalls or skips a bit then dies it will restart but then dies again any ideas to what would be causing this to happen any ideas are greatly appreciated...

 

huge vacuum leak maybe? make sure your egr isnt stuck wide open or any of the big vacuum lines are busted off like pcv valve or for the brake booster

 

Maybe the same issue?

Does somebody have an idea on how to isolate this issue. I have no time at the moment to dig into the schematics and figure if we could measure the output signal of the crank position sensor.
