07 rancher won’t start in cold weather!

I have an 07 rancher 4×4 es that won’t start when it’s cold out. When you go to start it the fuel pump doesn’t come on and since there is no fuel won’t start. Starts no problem in the summer. I’ve been stranded on lakes ice fishing and am scared to even take it out again until I maybe find out what’s going on. Any help would be appreciated! Thank you
