New forum member here living on a farm in Central MO. Brutally cold last couple of days. I have a 2010 700 TBX that gave me problems today. I went to blade snow and the 4wd didn't kick in; TBX was in a 35F building, but -7F outside. Next I tried to move in the snow (4-5") with 2wd. I was moving ok, so I tried the 4wd drive again. The engine died. I tried to restart, but dash is blank and efi doesn't respond. Battery is fully charged, lights and winch work fine. I would really appreciate any suggestions on where to start to resolve its problems. the TBX is my go-to workhorse on this farm. Thank you in advance.
