random 10 minute lockout prevents engine start

Random security lockout prevents the engine from starting for 10 minutes. Has happened about 10 times in a few years but seems to occur more often as it ages. No easily identifyible cause for the problem and can happen at any time, cold start, got start, day or night, hot or cold conditions, in a garage or in an empty parking lot. No clear resolution either.
