09 Nytro FX went into limp mode

[schwaaa31]

So, my Nytro went into limp mode while trying to load it in my truck one morning a few weeks ago. I shut it off and turned it back on, same thing. Got it in the truck, let it sit for 5 minutes, started it, and it was out of limp mode. It had got warm and rained the day before, and then got real cold over night. Maybe moisture froze somewhere on something??? Any ideas? I'm leaving for a trip this weekend, and would like to have a running sled. There were no codes on the dash when it happened.

Throttle cable to tight? Maybe got some ice and snow in there.
