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'?
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.
