All my dash light come on, the check charging system and low fuel come on. The speedometer goes to zero. It does not do it all the time only when I drive the car too much. The car runs fine with all the dash lights on.

When the problem occurs the alternator light comes on then goes off? If so then the unit it failing intermittently which is common. When the light is on can you try this guide to confirm the charging voltage.
