106 xr not working problem?

Friends, my car is 106 & nbsp; XR & nbsp; sometimes it does not work,
electricity is coming, the car is starting, everything is normal but it is as if gasoline is not coming
I tried to knock it once 1 did not work
also when the car did not work 5 10 15 minutes or waiting for half an hour it works! It's ridiculous but the vehicle seems to be kidding me
