Clio 99 Fallas

Estimated I have a CLIO 99 that walks the rather but after a while stops and starts but stops again and after letting it rest normally as if it happens nothing, someone who can advise me since I am new to this.
thank you so much

Check the chopped sensor, it is located in the union of the box with the engine on the top, it is small, this is in charge of the boot signal, the ignition of that engine is reprogramable, it is self -reset every time that you activate the ignition in the engine, possibly this is the cause of your problem ... greetings ...
