Hi,

This sounds like a fuel issue but there are other reasons for a hesitation.

Here is a guide that takes you through the common causes:

I suspect the issue is the fuel pump but this would need to be tested before we just replace it.

Let me know if you are able to test the fuel pressure while the issue is happening. Let me know and we can go from there. Thanks
