Y Reg Mondeo 2.0 Diesel
During a long drive at night, momentary loss of electrics / headlights on several occasions. Guaranteed if I take it to the garage, it won't do it. Does this sound like an alternator problem?

sounds like a loose connection somewhere - start at the battery connections, then fusebox, then around the ignition switch. If you can't find it check everything again, giving the cables/wires a shake with the lights or radio on and see if you can make them go off again.

Unlikely to be alternator as battery would supply electrics for a while after an alternator failure.

Do the electrics come back on without any intervention on your part? Does it happen on rough surfaces? If so maybe loose connectors, relays, or corroded earth cables. If it's a partial blackout it's more likely to be the former, if total failure the latter
