Intermittent stall problem 92 si hybrid

b16a3 transplant. Nasty wiring under dash. It's been towed 3 times,
mechanic's diagnosis first time "loose wiring", second time it ran ok
for mechanic, third time replaced ignition control module. It stalls
at any speed intermittently, I found the work around was to downshift
a gear or two and it will fire back up. To start it when it dies at a
light the work around is to put it in gear, release clutch, and
engage starter, on the foreward lurch it takes off and runs. Next
stop, another mechanic? Electrical specialist? Part it out? Any
thoughts appreciated
