Is there a check engine light on or trouble codes stored in the PCM? (powertrain control module)
How many miles are on this vehicle? The first step is to check the PCM, but you will need a code reader to do so, or bring the vehicle to an Autozone or similar store, and they can check codes...free. I'm not sure what the diagnostic result was for CKP replacement, I'm assuming there was a code(s)????
Wow...that is a first. A engine that stalls out intermittently should have a code stored in the PCM. So, with that said, what condition are the spark plugs in?
For a vehicle to have this condition and not flag a code is an intermittent issue that, to be very honest, will require scanner connected to the DTC, and when the vehicle is running, and it stalls or dies with the scanner connected, will allow a tech to see what is going on with all the engine management components. It also may be fuel pressure related, and I'm assuming the pressure was not checked with a gauge at the time of engine stall? The spark plug brand should not be an issue, and I'm also assuming they were replaced because of this issue, and the problem still persists. As far as the alternator being warmer than usual, how does one know this temp value?? I have never heard of a temp spec for an alternator. What is the battery voltage reading cold and what is the reading when the engine is running?
They already have checked the DTC. The DTC stands for diagnostic trouble code, and none were found.
I would recommend checking the fuel pressure with a gauge, and monitor the fuel pressure when the engine stalls. This will have to be ruled out as a possible cause.
ok.....

Unfortunetly there is no engine lights on. (no code)
I had tooken the car to Autozone and they could not find any codes, also the spark plugs & wires are about three months old ( autozone brand) does that makes a difference? battery was replaced and I also noticed the Alternator is getting warmer then usual. I found that awkward.
Thanx
I agree, It seems so odd for the car to shut-off with no related problems. Can the DTC be chked at autozone witht their machine?
Yes none were found...well thanx for the feedback.. I will continue to try and find the problem.
