91 740 turbo ecu failure? 700

i got my car back today, i had my mechanic go through it and he checked the ignition system, my turbo, fuel pumps etc... everything was fine. i had him swap the ecu with another used one as i think that it likely what it is.

my car did this last spring, and i went through all sorts of hoops and finally i noticed that when it acted up, if i shut the car off and turned it back on it would be fine. i changed the ecu and it has been tip top for 10k miles.

when your car acts up, does the check engine light come on? mine does not, but did when my AMM went bad. also how are your turbo hoses? i changed all mine as they were old and it caused a similar condition.

good luck, and here's hoping it was my ecu.
