Battery is good but it still won’t start

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. When you say "the battery is working" - has it been tested and verified to be fully charged and able to accept a load? You are saying it happened just once - It really will take some duplicating concern to recheck and figure what happened to get there.
