help disco td5 2002

my td5 starts and runs well until it reaches normal runniing temp then it syops and wont restart until it coolls back down ,any ideas

Do you have any diagnostic kit, i.e. Nanocom etc.to look for any fault codes? How does it stop - does it just cut dead, or does the engine slow and chug or cough to a halt?

hello spong
yes the later coughs and chugs to a halt i bought a hawkeye total to try and solve it but the codes it gives are not in the book 3012,3016,3032,and 3044

So might be a drop in fuel supply, is the pump making any odd noises when the engine starts to die? Unlikely to be air intake problem, but could be electrical, with a sensor giving weird readings when it gets warm and causing the ECU to do the wrong thing.
Is there a prefix to those fault codes, e.g 'P3012'?

no there is no prefix to the code but i noticed that the revs increase and decrease just befor it stops

As said, you need to get the codes read with a Nanocom really. Could be a fuel pump issue as suggested, or CPS, (Crank Position Sensor). There are not many things that actually make a TD5 stop.
