First heres my ignition system- msd pro billet dizzy, msd 6al-2 box, msd blaster 2 coil. Started a month ago car will start normal drive normal once temp reaches 180 car will shut off at any speed like key is turned with no restart for around 2 hours. When shut off happens i have no spark at spark plug or in between coil and dizzy, first thing i changed out was tfi still no good then i put a new msd blaster 2 coil (had a choice between msd or and accel coil at pep boys) that didnt do it. So i exchanged tfi for new one that didnt do it. Now i finally woke up and picked up a Equus 3145 code reader started car drove around till 180 degrees then pulled in garage shut car off waited couple minutes then start usuall after a minute or two car shuts off, these were the codes first 27 then 85, 67, 15. 27 is the code of interest 67 i think was i didnt hold clutch down during scan and 85 cause of stuff deleted on car. thanks any help appreciated driving me frikan nuts!
