Has been checked to see if something is draining battery. nothing found. Replaced battery a couple times. Happens more in cold weather but still happens if I don't drive the car for a day.

    Sounds like the alternator doesn't have the power anymore to adequately recharge the battery which will cause a slow constant drain on the battery until it won't start. Get alternator tested and replace if necessary.
