Hello

I'd start by checking the fuel pressure with a running engine as if is low you'll get this issue

If the connections to the fuel pump are corroded or damaged then the pump could stop at any time or could not be running at full speed. Check that its relay switches in and out and the relay contacts are clean and bright – replace the relay if in any doubt and do the same for the fuse,

also consider changing the fuel filter as if this partially blocked this too will reduce pressure.
