I have never heard of any issues with bad batches of fuel from BP, but have read quite a few coming from Caltex. It's always a possibility however. I'm not sure who does it, and I think it could be expensive, but you could get the fuel tested. If I had a feeling it was fuel I'd park it up and get it tested. Drive too far, cause damage to the engine, then it'll be a shit-fight trying to get BP to cover a rebuild. Fingers crossed it's something simple and just coincidental!
