Sounds very much like an electrical problem of some
kind..............as if the fuel supply is blocked, there is no chance
of restart after a short time, without having cleared the blockage
first.

Not always. If the float valve is partially blocked it can allow a little
fuel to trickle through which in time will re fill the float chamber, but
not enough to run the engine, so when the bowl has emptied the engine
splutters and dies from fuel starvation.

I wonder if you bothered to read what the OP had to say in her post?
Seems the fuel system has been looked at very closely already, and as
the system on a lawnmower is extremely simple, a fuel blockage is
highly unlikely. Seems to me it would be well worth removing the plug
when the mower stops, as if there is then no spark this will be
immediately obvious, and the problem can then be easily fixed.

On the other hand if there is a good spark, then I would suggest
trying another carb, as on anything which is used infrequently and has
modern fuel it it, there is a good chance of internal deposits inside
the carb, which may be causing some strange problems, and generally
cannot be removed even with ultrasonic cleaning.
