Fuel pump cutting out.

[Yatz]

My Chimaera 4.5 has developed a curious problem. The fuel pump suddenly switches off, or at least that's what it seems to be doing. I can be driving along and suddenly the engine just dies. If I press the fob on the key just as you would when first starting, the pump comes back on no problem so it's working ok, it just likes to turn itself off for no reason. It seems to do this when the engine is hot as the problem generally happens as I am returning home from a drive. Is this a common problem?

Thanks for the feedback. At the moment the problem seems only to occur when the engine is hot, when I have been driving for an hour or so. I can start the car and go for a short drive and everything is fine. When it cuts out all I have to do is press the fob as you do when turning off the immobiliser and the engine starts again so it's basically the immobiliser coming on which is, of course, the fuel pump turning off.
