86 S-10 Blazer won't start

I was driving down the road and the power on my 1986 S-10 Chevy Blazer 4X4 dropped off the board. I tried to start the "2.8 injection v6 with only 75k miles" up again and had no success. I got a code of (44 Oxygen sensor lean).

If anyone has an idea of where to look and how to do a fix this problem, I am all ears.
