Try getting some gas line antifreeze and using double the amount for at least two tankfuls. If that don’t do it, you might need to try higher octane gas, an octane boost, or both.
If that doesn’t solve, you might have to get the tank purged.
A dash of methyl hydrate may solve the problem . Sounds like you have water in your fuel, one litre to a tank or half a tank. You can get the Methyl Hydrate from Home Depot.
If this thing performs like you said it does it would through a code
like if it was a fuel problem P0300 multiple cylinder misfire
does it run normal after the engine reaches operational temp.
or does it run bad all the time in freezing weather
another thought would be a restricted exhaust but outside temp should not matter
