Peugeot 206 HDI 2.0 90cv, I stop.

Hello, how are I such, I have a problem with this 206 HDI, when the car heats up, it stops, usually passes when you ask the engine.
I have proven that the car stops because it stops coming to the deposit pump and I have checked and the machine tells me that there is excess pressure in the circuit.
Well greeting and I hope you help.

Put the diagnostic machine, with the car running you and check that it marks the diesel pressure parameter and post it here.
