Problem with Toyota Yaris

[addavid]

HI There 

we have got a Yaris diesel from 2008

since a few weeks it is playing up and the garage we normally use could not find anything wrong and suggested that we take it to 

a toyota dealer which we did,

problem is as follows.

we are driving normal and suddenly we loose the power of driving.  We cannot axilerate to go faster.

We stop the car switch of the engine and after 2 mijnutes we start again and it goes normal again

Problem is that the computer on board does not show any fault codes at all that is the reason that the Toyota garage send us back

home until it happened again and it happens quite regular now.

 

Is there anyone who has had this problem before and tell us what could be wrong

 

we would be very grateful

 

Thanks for reading and helping us
