Peter, the only way you can test a capacitor is by removing it from the cct, obviously not very practical. In general, if an electrolytic capacitor fails it's usually because it's dried out and often has a bulging top. Having said that, capacitors are usually pretty reliable and failure is normally due to extreme age or operating under harsh conditions.

Has this been working ok in the past and is the problem fairly recent? You haven't made any changes? If so it certainly sounds like a loose connection/dodgy joint somewhere, seeing that it's intermittent.
