What's causing the intermittent power loss in my Toyota RAV4?

I have a Toyota RAV4 CVT 2014 petrol, that has an intermittent loss of power when trying to pull away particularly from a side. I'm not sure if it's the tyres as they are Bridgestone Dueller HT 235/55 R18 fitted from new with an average 6.5mm tread all round. I have taken the car in to the local Toyota main dealer twice and they say unless they can replicate the fault they cannot fix it, not unreasonably.

We had similar problems with a very new pre-production 8-speed torque converter transmission on Wednesday. Suspected a software fault. Took another out and it was perfect. Given that the tyres aren't the problem it must be with the electromagnetic CVT clutch, but problems with Toyota CVT are very rare.
