hello every one

im having a bad time sens my 2003 q45 start fine without any problem but after 5~10 min drive the engine stops and wont start agine tel i let it for 15 min .
the car keep tilling me it is the fuel cap or fuel pumb or fuel filter so i replace them all but no change.
i try to take the car to the dialer but no change. i try to check for any codes using code reader but no code error
there is fuel in the injectors but no spark is it passable that i hove a bad knock sensor or what could it be

So I replace the two crank sensors with a new pack from the dealer and the car worked fine
think for your help guys

to NICO!

If the car cuts off consistently after a short drive, your Infiniti dealership should be able to recreate the problem while monitoring all of the parameters with their diagnostic computer, Consult.

I doubt a knock sensor is the problem... you should get a code if it's bad.

I used a diagnostic computer and it shows two errors
"p0340 CMP SEN/CIRCUIT
"p0340 CMP SEN/CIRCUIT
what is that and dose it stops the engine.

I was having this problem with my 98 q45 last week but it cleared up. . . . for now. I would like to know what those codes mean as well.
