battery light on - off- on

I have a 2007 compass with 96000 miles. a few says ago the battery light came on while driving. I had the battery and alt tested. Battery as OK with full charge and the alt was out putting 14.5 volts. Once the engine is shut off and restarted the battery light does not come back on for a while,10, 20, 30, minutes 1 hour of driving before the battery light comes back on. After 1.5 hours of driving with the battery light on and the head lights on I had the battery and alt rechecked without shutting off the engine so as to keep the battery light on . Battery OK fully charged alt out put 14.5 volts. What is going on?? thank you in advance John

Could be a slipping belt. Any noises? Also might be wiring to the alternator, or the regulator/brushes starting to go. Makes poor contact when warm...
