Weird one here....70mph on motorway and it throws a brake warning light...couple of beeps from the dash and the engine cuts out.. Left it for a couple of minutes and it started right as rain again. Its now done this around half a dozen times ranging from two minutes driving to two hours without cooking out. Only code that came up was a low pressure at the turbo boost regulator and was told it could have been a while ago the code registered but still doesn't explain the sudden engi
