In reading your problem, my thoughts were from the past, the distant past.

In the old days, with which I am familiar, this would have made me think about the fuel tank vent, or a clogged fuel filter, or fuel pick up screen.

That said, I believe if this were the case in a modern car, a code would be set due to low fuel pressure.

Just food for thought,
