I thought you were running on propane. If you're only running gasoline, it shouldn't be a problem. A slightly stronger antifreeze mixture is good but you do have to have water in it. Straight antifreeze only in good to -15 F or so. You also don't get the anti-corrosion protection either. You can go slightly more strong but not undiluted. I drove in Minnesota one winter but I don't remember how strong the antifreeze was then. Also, 50+ years later, I'm sure there's some new research into it.

Keep in mind, the lower the freezing point in cold weather, the higher the boiling point in summer. It also increases corrosion resistance all year. Generally, the antifreeze portion of the mixture never really goes away. Park it in a field for 10 or 15 years, the freeze point will stay the same. The anti-corrosion on the other hand fades after 5 years or so.

I think 60/40 Ethylene to water is strongest, but again, there is so much movement forward that might be outdated. To be honest, I'm not really familiar with Canadian geography. I'm familiar with British Columbia and NewFoundland, beyond that, I'm lost.

New week, another test lol. Took a drive and started stalling again after driving 10ish minutes. Engine cranked until I turned off the key, then started fine? Had difficulty getting up to speed it almost seems like a gear is stuck as sometimes it'll give a very aggressive shift down then go fine for a bit but also feels like a lack of fuel with the way it revs instead of normal.

I'm going to toss in the towel and list it, hope someone with time and money can handle it but I'll still appreciate assistance here to help the future diagnoses.

I'd upload the video of it stalling but i dont know how too...

Upload it elsewhere, youtube, or similar places, then link to it here.

Did you test the fuel pressure?
