Not starting when on a hill

[Tonywft6]

Hi every one i have a T6 2018 204 ,my drive has a slight slope when the fuel gets to quarter of a tank it will not start , i had it look at by main dealer how charged me £600 for investigation work
and a fuel pressure sensor and fuel filter fitted , they commented it was an intermittent fault that they couldn't fix !!! has any one had a similar problem
thanks Tony

I had similar and Vw couldn’t fix it. It dragged on for nearly 6 months and I ended up rejecting the van and getting my money back.

Might not be the answer but you tried reversing on your drive?
