150 OX66 shutting down

[dana9140]

Started last week out of the blue. 2000 150 OX66 will run good on plane @ about 3600 rpm for about 1to 2 minutes. Then it will just shut down . Put it back in neutral, it will start and run for about the same time and shut off again.
I put new water seperator and new plugs . Now it will go into idle instead of shutting off. Put it back in neutral and off it goes. Will run longer if i stay under 2800rpm.. i did run out of fuel 2 weks befor problem started. All Help is appreciated.

you need to have your vapor seperator tank filter cleaned. your loosing fuel pressure.
