Rhino is dying in slow trail riding conditions

I know I have been changing a lot of crap on mine lately but the last two times I have had it out on some of my technical trails I have came across some downed trees and had to turn around on the really tight trails.  I am running in low and when I go back and forth between low and reverse a couple of times it will start dying if I am not giving some gas.  Last night after it died several times it took a few minutes for me to get it started again and once I got moving and out of the slow stuff it was acting fine.  Has anyone else had any issues like this.

clean and lub the icu on the tb...mapping??

I was afraid it was in my mapping.  I am taking a whole lot of fuel out down low to get my a/f right.  I will take it out again tonight and if it does it again I will unplug my fuel controller and see if it still does it.  Im about to do some more work to this thing.  I am about to swap cams out for a Stage 2, slug the wet clutch, and put in gold spring.

I think I have my tune all worked out and it is running great.  I am still getting some dying when I am in low and crawling around.  It's like the idle is too low with the big cam and when I come on and off the throttle it drops the rpms too low and doesn't recover and die.  Is there any way to up the idle rpm a little bit.

Mine done the same thing when we were still testing on it.  James and I took it out for a final tune and added some fuel in the idle, low and midrange.  It cleared that right up.  Seems like they run good a little of the rich side down low.  I think when we got it good, it was right around 12:1 in the low rpms and light throttle.

The only problem I have with my tune, is it don't like going down really long hills in low range off the throttle the whole way.  When I get to the bottom, it dies.  Starts back up with some throttle.  Keep giving it throttle for a few seconds and it's ready to go.  I'm thinking I may be getting to much fuel at 2-3k rpms at 0-10% throttle.  I only have this happen on one trail that I've ever been on, so I'm not really worried about messing with it.
