MY 1988 EA Ford Fairmont drives and handles well, but sometimes at more than 90km/h it loses power. My mechanic can't find any faults; neither could the Ford dealer.
YOU don't say whether it has throttle body injection or multi-point fuel injection, but it sounds to be a fuel-supply problem. It could be an intermittent fault with the fuel pump, or even a blockage in a filter or pickup. If it is the fuel-injected engine I'd have the injectors cleaned.
