It started and ran perfectly for the first 3 cuts of the year but the
4.5hp Honda has played up this evening. It started without problem, ran
for one to three minutes, backfired then stalled. Tried it five times,
same result.
Grateful for any suggestions.

Weak mixture.
Clean out float bowl as mentioned above.
Check that the fuel tank cap "breaths" - do this by removing the fuel line
and letting the tank drain into a container. If it slows down and stops then
the breather is blocked.
How old is it - you might have to have the carburettor cleaned as the jets
in Hondas are very small and prone to blocking - (There about 16 small
orifices in an 11hp Honda that can block.)
You could try "Carburettor Cleaner".
Remember to always switch off the fuel and run it dry when you have finished
with it. That will help prevent this sort of problem.
