Universal M3-20B keeps stopping

All of a sudden, my Universal M3-20B is repeatedly stopping. Happened yesterday for first time while underway. Was able to restart right away but kept stopping suddenly after a few minutes. Just sputtered and died.

Was able to get back into the slip by repeatedly restarting. Guessed it was something to do with fuel system. Primary filter looked ok. Replaced secondary, bled the system, and verified that the lift pump worked.

Ran the engine at the dock 30 min to ensure it all looked ok. Got out of the channel and raised the sails and it died again. After the sail, made my way back by starting it over and over.

Other symptoms/issues: I believe I have a bad oil pressure sensor with a high reading (even before cranking). Also on way in today noticed a lot more vibration than normal.

Temp is ok. Water circulating fine. Plenty of oil.

Looking for ideas.

Thanks.

Re: Universal M3-20B keeps stopping

Most problems like yours are fuel related.
Check that fuel tank vent is clear.
Check that your fuel line is not partially blocked.
Make sure the pickup tube is clear. Some have a screen on the bottom end that needs to be scrapped.
Make sure that your tank is clean.

Then check that the mixing elbow is not plugged up.
