EPS stop engine light

Hi, I am in the middle of my conversion. The bus sat over the winter and I restarted the work in April. We turned off the batteries while it was sitting and have turned them on a few times and started the bus. Today, we turned on the ignition but didn't start it. There was a beeping for the air pressure warning and after 5 minutes of that I started the bus to build up enough air pressure to turn off the alarm. About the time the pressure built up enough to kill the air pressure alarm, a new warming light came of that said EPS STOP ENGINE. A Google search said it refers to Electronic Power Steering and to get it serviced. The power steering fluid reservoir seems to have fluid up to the add mark. It is kind of pink in color.

I don't see any leaks but I may be looking in the wrong place. Has anyone seen this error? I am not ready to take this on the road yet. Electrical is half done, plumbing yet to start and in the process of replacing my rear lights.

And I still have that annoying beeping going on. Can anyone advise?

EPS - Engine Protection Shutdown. Red light and the warning beeper/buzzer. For your year (1999?) it'll probably be low oil pressure/over temperature/ low coolant. Check coolant level first, since I doubt it warmed up enough to get the coolant that hot.
