It sounds like your engine is running out of gas due to a clogged filter.
The little bit of gas that manages to get through after it dies is enough to get you going a bit more till it starves again... etc.
I'd replace it. It's inexpensive anyways... and right, you might very well have floaties. The filter could be doing it's job.
Getting the tank cleaned could be the next step.
2 cents worth...
Good luck!
