2003 Suzuki 90 DF

I was running my boat around 4500 rpms, everything think sounded great and had been running perfect for about 5 miles when it suddenly just cut off and it would not restart.

I’ve check for spark on all cylinders already and that it good.

I recently replaced my high pressure electronic fuel pump and I can hear it cycling when I turn the key to the on position.

Tried replacing low pressure fuel pump today and that didn’t help.

Replaced my fuel filters one under the engine cowling and the water separator on the fuel line.

Still no luck. It has three lights on check engine, temp and oil all steady red not blinking when I turn the key to the on position. It beeps every 5 seconds or so.

Any idea what I can check next
