Not a problem common in Scotland, but take off the muffler & try again.
If it runs full power ( for a few minutes ) you have a blocked muffler.
IT WILL BE VERY LOUD & CAN DEAFEN SMALL CHILDREN.

I just fixed a small engine with the same symptoms. It turned out to be a lose head bolt. I do not even know how it started but it did then would stop. This is a very rare issue so take this as needed.
