Engine cut out on incline

[Speartip]

I’m not sure how the fuel pickup inside the tank looks or is designed .
Since it happens mostly on inclines does have something to do with fuel pickup line in the tank . If on an angle or changing gears . Fuel sloshing around fuel isn’t being picked up like it should

On a side They had it for 2 months ?? That’s nuts

When was the last time the plugs and wires were changed?

I am not sure. Would they have changed them before I purchased the car from the lot, last Dec?

The dealer is now saying they can't replicate the fault and therefore have nothing to fix...
