I am in the lower 48 trapping an area of about 508,000 acres of trails/2tracks with very limited maintained roads. What do you all carry in terms of survival kit to keep yourself going if something happens (break down ect)

Last week I was out and my 4wheeler quit on me several miles from the road I dropped the truck on. Fortunately it is still warm down here making it a pleasant walk back not the -20 to -40 it will be in a few short months, and I was at the top of my line not 15-20 miles down further..this event has given me some pause as to what I keep with me.

More important than any tool is to have the clothes readily available to withstand the worse weather you can possibly encounter. Then I'd argue 2-3 means of lighting a fire, The mini road flares are awesome. A mora knife, a 2 quart pot, first aid kit, some cordage and a synthetic sleeping bag.

I like Mors kochanski books. He was a Canadian cat and has the cold dialed in pretty well.

well said

#1= means of communication.
#2= means of communication.

#3= fire-making tool.
#4= water that is not frozen.

The rest will depend on your situation and problem. Your machine of choice should ALWAYS carry basic tools and parts specific to that machine.
A small shovel, (those folding ones can do a lot of work and take up little space), and some jerky or pep sticks stay good if wrapped properly, and are usually in a pocket of mine, anyway.
Again, the most important tool you can carry is a reliable way of communicating with somebody that can help.

Road flares are an excellent firestarter, I've never seen the mini ones but have packed the regular ones for years. A spare set of dry clothes is something I packed for years on the snowmobile and need to get back into the habit of. Shovel, winch or ropealong to get your machine unstuck or back upright, and an ax. A chainsaw is great, but an ax is more reliable, if I figure on needing to cut blowdowns out of the way I carry a saw, but an ax is a permanent fixture on my snowmobile. Not sure where you are and how much snow you have, but if there is enough to run a snowmachine you should have a pair of snowshoes strapped on it.
