The snowblower starts good and runs good, then after about 15 minutes of running it starts to run rough and on occasion will start to miss fire through the muffler and finally stall and will not re-start, until a day or two later, fresh gas and new plug ????
i have seen this when fuel tank is not vented loosen the cap when it starts to happen if this helps it needs a new cap

This sounds like a coil failure. It's fine until it gets hot, then the insulation fails. They're not hard to get - any B&S dealer will have it. Ebay will be cheaper.
