Boat stalls under load- starts right up

ideas? I don't have a oil pressure switch only a sender and sensor. I'm going to dump and inspect the contents of the fuel filter but filled up before launch and vent works fine. Hoping somebody else experienced the same problem. Thanks

It seems to be stumbling at low speeds (RPM). I'm going to put another set of plugs in maybe a cap/rotor if I can do it in the water. I'll report back. thanks

Check the coil too. Plugged fuel filter?
