Fuel starvation

So my v8 has had this problem which I'm fairly sure is fuel starvation. When I'm travelling at about 60mph the engine will splutter and loose power, it even happens at lower speeds if I get a bit carried away on acceleration. I have to pull over and let the engine idle for a bit to fix it. Recently it's also became a problem when travelling at lower speeds and with any level of acceleration. This is only a problem at low speeds when the engine is cold though. Anyone know what could be causing the fuel starvation? Also what could be making it so much worse when the engine is cold? 1999 Land Rover Defender 110 td5 station wagon

I'm not sure if the Defender is the same set up?

I had an early 2 door Range Rover 3.5 on carbs that had the same symptoms as you describe.
It turned out to be the small pick up filter in the tank, which was getting blocked when demanding more fuel on demand.
It became apparent when I rigged up a temporary fuel supply to rule out everything else.

I removed the old pick up filter, and replaced it with a plastic gauze filter from a spray gun.
Never missed a trick after that!

Also worth checking if the pump is actualy working at full flow too. 80" 80" 86" 88" 90"

The Defender setup will be pretty much the same, I'll take a look at the pickup filter when I next get the chance. When I went to the garage last time they used a fuel pressure meter and it appear to be at the correct pressure, they couldn't test it under load though. 1999 Land Rover Defender 110 td5 station wagon

So to update the situation, I'm not having a problem with fuel pressure. The next thing that draws my attention is the electronics, I have bought a brand new distributor to see if it solves the problem. Will update again once fitted and tested. 1999 Land Rover Defender 110 td5 station wagon

Update time:

New distributor fitted yesterday. The problem has now been completely fixed! How nice it is to cruise down the motorway at motorways speeds
