Esteemed BTDT's,

I've been driving my latest  '91 Avant for several months
now with the IA III+ chip (very fast, very smooth). Three
days ago, while accelerating from 3rd to 4th--+/-4800 revs,
I heard a quiet Pop, and all went dead. Shortly after the
engine would turn over, then die. As fuel pump and timing
belt are fine, I checked fuses and found one of the red
capped motor fuses blown. I replaced the 5 amp with a 10,
per the manual, and voila!!

This morning, at almost the exact same location, weather and
rpm's , it happened again, but this time with a crack. I
found no problem with all the usual suspects, including
fuses. The car will start, but then sputters and dies. And
btw, I get NO FAULT CODES.

Has this happened to any of you, particularly those of you
running IA chips? I'm perplexed, as is my mechanic, who
wants to ship the ECU back to IA for diagnostics. And
Bernie, though I know you would not approve, I replaced
countless fluids, hoses, sensors, etc. before chipping the
car. Help!!!
