Mechanical problem with my Suzuki Vitara 2001

Hello!! how are you?
I have a problem with my vitar, fix that my problem was: that we were behind a truck, first, we were very slow and my truck began to make up and no longer accelerated, the engine lost revolutions, and better turn it off, then I wanted to start it and I did not answer, wait a while and slowly started and then it was normalized.

Another day, let's go in the traffic with my potato and I no longer accelerate, and I began to make up the engine again, this time I do not go out but the revolutions fell again, turn it off and press the fuses, and I do not start, but it has alarm and we move I do not go out, and I get to my destiny without any problem, I would like to know what happened or what problem can have.
Thanks for your answer, that are well !!!!

For what you explain, it seems to me that it can be the diesel filter that is dirty and sometimes not enough fuel is passed and that is why he cannot revolutionize or it is difficult for him to start when he stops. I recommend that you change the diesel filter.

Hello it seems to me that you should also do a pressure and flow test to the fuel pump

Thank you very much for your comments and answers I will take it into account

Hello, you can have problems as others said with the ffilter, the pump pressure, an air suck
