SPN code 94

Bought a 2015 Mojo and have been out on it a few times and yesterday the "check engine" light came on and threw this code. Looks like it's something related to fuel. Anybody have any experience with this code? It would take about 5 seconds to start and then after 30 seconds running would stall out.

I am just chronicling this in case some other owner has this code and issue. Preliminary report from Atlanta Marine is that it is an oxygen sensor. They will let me know more by the end of the day.

needs a new filter. solved.

What type of filter and where is it located?
