i have the same problem and i found out the its a fireing problem with the computer it randomly does it and gives no warning. the computer has a short in it and its effected by static when the air is moist or real hot its gets worse. after several attempts taking my 90 to the garage and 3000$ later i still had the problem.

i went to a local junk yeard spent 150$ for a used computer and its not done it since.

Caution if you decide to get a cpmputer at a junk yard or parts stores once installed not returnable.

also check for any misfireing thats a common problem too caused by a bad wire or cracked coil.
