2007 Yamaha 150 4 stroke issue

Robalo13

I have a 2007 yamaha 150 4 stroke that ran fine all day until I was idling and it stalled.  Limped back on one motor.  Checked gas, no issues with filters.  No water in gas.  Turn the key it starts for a couple seconds then stalls.  Oil pressure showing all the way to the low side but checked oil is oil is good and topped off. Oil sensor gone bad?  Where is it?? Does the Yamaha have a OBDII connection for reading or does it have to be Yamaha connections??  

Much help needed!!

Are you using ethanol gas?  Could be fuel injectors need cleaning.  Have you noticed any reduced power on that motor?

I don't think it has an OBDII connector.
