Trailblazer 302 error codes???

[RAyJ]

I have a lightly used TB 302 EFI that I need to run as a generator for a few days. It started fine, ran for about an hour then died. the display showed "OIL" and "085". Oh no, checked the oil and it was low so I added enough to bring it back to full. It didn't want to start for a while so I let it sit. an hour or so later it started. Now it will run for 20 40 minutes, then die. the error code is OIL and 084. I did a quick check through the owners book and can't find any reference to these error codes. Anyone have an idea? I don't have the serial# but it is about a 2010 or 2011 model.
A tornado took out the neighborhood power line last night, trying to keep the cold stuff cold until the line is rebuilt. Thanks!

Well, what I thought was an error display is just a countdown to the next oil change. still having an issue with it only running 30 minutes or so, it may have too much oil now and I've been told that can cause erratic fuel delivery. Thanks Dustin in Tech support!.
