Unless there's something odd about your battery and alternator, I would wonder about the winch / wiring etc.
Your truck is likely less than 6k lb, on icy road - so anything beyond 2-4k lbs pull would make your truck sliding towards the other truck.
A winch stalling at about a third of its rated load is not very common.

My truck was on pavement, actually, there was a nice sun spot right there where I positioned my truck. I was running the engine with foot on the brake while winching. But, you have a good point. I don't know how much that truck weighed, but he was stuck fast till we dug the ledge out from the tires.

huh... The other truck - if in order to free it you need to lift a wheel or an axle out of a hole (move the truck vertically), you may need a pull larger (or much larger) than the other vehicle's weight (imagine pulling something stuck against a wall). So if your truck was on dry pavement, it may be closer to rated winch capacity.

Yeah. She'll be fine. Glad she worked for you when it was needed!!

It would be interesting to put a voltmeter on the terminals. It has a 5.5 HP motor, which would be a draw of ~350 amps even if the motor is 100% efficient. Those cables are so large that voltage drop won't be a problem. The alternator can supply 100, I suppose, so the rest would need to come from the battery. I voltage measurement would be an interesting experiment sometime. ;)
