One of two things:
Either the ignition coil is failing, which is not un-usual..
When it dies, have a known good spark plug handy. Plug it into the
spark plug wire, ground to head and look for spark..
Also, do you have a low oil shut off switch on that engine? It'd have a thin, probably black,
single wire going to it. If so, those are known to fail (especially on generators). They kill most
of the spark...
IF you do have it, just un-plug it to by-pass it. It won't hurt anything but won't be a "safety" should you let your oil level go low...
Both of those cases either kill most or all the spark.
Posting a full engine model # of the engine would help check the parts list to see if
your engine is equipped with the switch...
.Please post back what you find..
