hi all

my legacy cuts out only on the motor way when doing speed 60 mph or higher? it only cuts out once and restarts fine the only warning i get is all warning lights come on and engine cuts of? and i loose stering so i dip the clutch and it restarts fine? the rest of the trip its great no problems it ok when normal roads


i put it into the garege and the lad said there was a fault on the computer and he reset the computer. but still the same problem??????????/

anyone ideas????
