Last week Car just died after driving about 15 minutes would not restart or crank. Waited about 30 minutes car cranked and started up, drove to PepBoys and car died pulling in to parking lot. Battery was original 2004. Replaced battery car was fine all week. Today drove about 20 minutes and car died at a light. will not turn over. Towed home. Have plenty of power all electrics working. Replaced the crank sensor in July. Any ideas?
