Thanks, not debating just commenting to what he said. 600A is over the rating for the part. Maybe it’s not the issue but I would get a higher rated part.

My S10 also has a 360V pack and on flat road doing 55 the draw is 40 Amps continuous. No, the max current is unlikely to be the cause of the fails. More likely a failing or insufficient pre-charge.
