under the engine cover there is a reservior that holds oil that is pumped up from the large tank. The reservoir has a plug on the top which is a float switch that switches the pump motor on to fill it. either the float for the alarm isnt working or the same float to tell the pump to turn on isnt working. check the connection of the wires coming off that plug.

Sounds like a head gasket, worn valve gasket, as my first guess.

There should be a vent on your gas tank cap . Open it up so the tank can breath. If no air gets in it creates a vacuum causing the primer to collapse and will shut down the engine.
If there is no vent turn the cap open a little just to let some air in but those tanks should be able to vent.

oil metering at idle really isn't important. The normal procedure is to run the engine on premix fuel and oil, and measure the oil from the oil pump at a certain revs, something like 2,000 rpm for 2 minutes, 6.0 to 6.5cc of oil. This information will be in the workshop manual. If you are going to do your own maintenance, you will need to get one.

Here's a link to Yamaha year ID. You need the letter that is below the number you have given to get the year.

It sounds as though it is starving for fuel. Check the fuel filter and replace if necessary. Also check and or clean the carburetor.

This is a known issue with the motor and the dealer used to offer replacement under the warranty. If your unit is not too old they might still cover it. Contact the dealer.

Yamaha actually lists the date of manufacture on the transom bracket or a label on the bottom

Make sure your shifter cable isn't out of adjustment . It must be in true neutral position on the engine and not advanced out of position. All boats have a safety feature that either cuts power to the starter or the spark plug and fuel pump. There are is a little adjustment room on either end of the cable . If you are in sure disconnect the cable at the engine and move the leaver on the engine to neutral . Then try and start up. The other issue that is over looked is a bad kill switch on the shifter or a corroded and or loose battery wire at the battery or at the engine.
