The lamp socket has two contacts. Although they may not appear burnt, many times, they have built up enough oxidation that resistance may be higher than should. When this happens, with high current going though, extra heat will build up and the result is - shorter life of bulbs.
Since you say the bulb lasted 4 minutes (meaning a while), I suspect this may be the case. The real fix is to replace the socket. You can try cleaning it but it is often hard to do it completely because of its cramped and near inaccessible configuration.
