First I would look for an air ingress problem with the fuel system, also a very badly blocked fuel filter can cause similar but that's unusual on a car.

where would you recommend i start looking

Lee,
Unless you're sure the fuel filter is recent and not contaminated then I'd change that for a start. Make sure the seals are perfect when you put the filter back.
After that looking for an air leak can be a pig. Sometimes it is easier to replace a length of rubber fuel hose near to the inj pump with see-through tube so at least you have a chance of knowing when the air is there and when you've solved it.
A start is that rubber fuel hoses tend to split where they are exposed to heat or are flexed by engine movement....and on pre-formed bends.
The ones from the underbody pipes on the bulkhead behind the engine that go up to the primer bulb/return connection might be worth a look.
