Hello, I have a 2023 Z3 with the indmar 400. It has 100 hours on it. The engine is cutting off while at low speeds and sometimes giving a primary fuel pressure fault. But not everytime. It seems to happen mostly in shallow mucky water (have to drive through a channel to get to the main part of the lake). It seems to correlate with a dirty raw water filter. But not sure why it would give the fuel pressure fault for that. Any help or ideas are welcome. Thanks.
