'91 200 20V Intermittent Start Problem

Your "dies immediately" comment is what interests me.

Once the engine is running the distributor is out of the picture and not an
issue.  Rule Out distributor.

Ask the Question:
Once running what would cause it to quit?
     No fuel or No Spark

Your comment "Turn key again, cranks fine, starts after about 2 cycles."
     Since it starts again quite quickly
     one would assume the fuel has not stopped.
     So electrical seems to be what is left.

I suspect the ignition switch.
     Intermittent contact when starting
     Intermittent contact when releasing the key

Further testing would show answers, but unless there I cannot continue.
I hope this gives you something to think about.

Car Particulars: Currently at 91K miles, was chipped with Stage III+ at 80K
miles - with Samco and all new coolant and breather type hoses.  Pulled
codes before and after chip - none present.  Here are symptoms:
Prior experience:  Started after ignition key turn and 2 cycles max.  
Now - Sometimes: Turn ignition key, cranks fine, "starts" after 2 cycles,
release key, then dies immediately.  Turn key again, cranks fine, starts
after about 2 cycles.
Now - Rest of Time: Turn ignition key, cranks fine, won't start even after
about 12 cycles.  Release key, turn it again, cranks fine, starts after
about 2 cycles.   
Have checked battery and charging system - all SAT.  Have replaced the
distro cap and rotor (yes, narrow one).  Any suggestions on what should be
