great story - because i can imagine just how you feel!
having read tons of stories about fuel filters and cold weather over the years i just did mine over thanksgiving weekend, at ~230 hrs, for the first time. machine has been running fine but figured they were due and didn't want to be doing them after the real cold sets in. even in "warm" conditions the bottom filter was a pain to change on the dirty floor of my unheated barn.
if you don't have them yet, get yourself some tools for the hose clamps! some discussion on that here:

if the filters don't solve your problem, check your fuel tank cap vent. if the vent is clogged the symptoms you described can result - the pump pulls vacuum on the tank and the machine is starved for fuel until it sits for a while.
