Renault Clio II helps that the engine fails

I have a Renault Clio Diesel II, 2005 with air conditioning
For a few months my fuel has been cut suddenly, at any time and anywhere.
Until the contact is short, it does not start again.
Clean the fuel tank, the filter and tank pump, storm the round trip and return pipes
I changed the fuel filter, I checked the inverters.
I checked computer failures and nothing
The computer does not detect the fault, only the engine is stopped
After starting it, it can work for 200km or much more and does not fail again,
other times it fails when you want ... every 2 or 3 minutes ... it's hell
Any suggestion?
Greetings and wish thank you very much Pablo

Hello Pablo, controls the fuel cut solenoid, sometimes the rubber tip that has and produces that type of failure is usually broken, or the engine does not stop when cutting the ignition or stops at any time during the march, luck and keep us informed, a hug.

Look nose because but it occurred to me to check the contact sheet
