It's happened three times now, firstly going round a right-hander in 4th about 35-40mph, again around a left-hander in 2nd about 15mph, each time with the throttle half open, then again clutch down coming to a stand at a set of lights (whereby the car stalled).
The two occasions when moving, there was a big hesitation in the power for less than half a second before the car picked up again.
My initial thoughts were airflow or fuel starvation?

How old is the car?
Do a search on here as this was a "common" (certainly more than 1 case
) issue on earlier cars (before 2008 I think).
Petrol cap/tank rings bells.
and 4.7 2008's. It happens/happened to mine a few times exactly how you describe. If you look at Redpants page I think he came up with a cause and solution to do with the vent tube that inside the tank becomes perished which causes a vacuum (??) in the tank.Do a search on here as this was a "common" (certainly more than 1 case

What was the weather like?
How full was the petrol tank?
I had this problem with my 4.3 V8. After a lot of fighting, AML diagnosed the problem and did £4000 or so of work to fix the problem.
There are a number of different problems, that redpants thing is one of them. The other problem is the fuel tank air purge line dumps neat fuel into the inlet manifold and that floods the engine. So the closed loop lambda system shuts down fuelling to the engine.
Manufacturing defect, should have been a product recall. Potentially fatal.
Answer above questions. Also, look for the thread on here. We've seen/done this one before!

Thanks John. I spent a good couple of hours researching it yesterday, including reading through the previous threads from several years ago. Will definitely gather that information before approaching the dealer with it.How full was the petrol tank?

Here's the Redpants thing they're referring to:
