I have cleaned the air filter and renewed the spark plug to no

Petrol starvation.

Not sufficient petrol getting through because as Martin says the filler
cap blocked and air cannot replace petrol drawn off at the same rate.

I once had a car that behaved like that but more like after an hour or so
driving. I finally twigged what the cause was when filling it up with petrol
one day. When I took off the petrol cap there was a big "whoosh" as air
rushed into the vacuum in the tank. A small hole drilled in the cap and
problem solved.
