No idea but a WAG might be, it's being asked to pump too much fuel to keep up with the needs of your engine? Pumps wear down and maybe it didn't do that in the beginning and probably had a built-in leeway above bare minimum.

If you're using the stock 20A fuse there is too much current draw with the BAP. Some have been successful going up to a 25A fuse, which most of us don't recommend, but I think you need a Racetronix harness to do it safely.

I had the same issue. I chased this issue for a year. I ended up changing the fuse block. I have not had the problem since. There is a recall for the fuse block.GM is going to replace it because of an issue with headlights shutting down. The wiring gets hot and separates. In my opinion this is another serious issue that needs a recall.
