'91 200 20V Intermittent Start Problem

[Michael Palatas]

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 next?  
 
TIA!
