I was wheeling on a trail and my check engine light came on. This Code P2099 post catalyst fuel trim system too rich come up on my Bullydog turner. The check engine light came come up and went away after 10 min of driving.

Can't say that I've ever had that. Have you tried running your tune back at stock settings? Could be a bug in the tune.
