Armada pedal stop working,

Hi everyone;

I have a Nissan Armada 2006 with 77k miles. Four times it has happened to me in the last 2 days, that I am driving and suddenly the gas pedal stop working, it only accelerates a little. (They tell me that is going in to safe mode)....... I turn the Armada off and turn it on and goes on like nothing happen.

The check engine light does not goes ON.... so I do not have a code....

I have consulted 2 mechanics one tells me it can be the sprocket the other one tells me it can be the throttle....


Have someone had this problem before?

Thank you very much in advance for the information!!!!!!
