Please help!!! My 98 nissan maxima is just dying all of a sudden while I am driving. THere is no warning and I have replace the alternator and mechanic can't seem to find the issue as it is not happening on test drive. It will start straight away but then sometimes die again as soon as I put it back into drive or reverse. All the accessory lights come on when the car dies.
Is something related to the distributor . Is not sending the right spark. Ask your local mechanic. My friend's car had that issued.

That particular vehicle uses coil on plug, no distributor, just a cam sensor.

Is it by chance dying like you had turned the key off? All lights on dash stay on?
I ask this because I use to run into this from time to time and the culprit was the" ignition control module".
Some were inside the distributor cap, they would get hot and disconnect internally. Once they cool off then it would start right up.
I used to be a Nissan tech years ago and I'm not as familiar with the newer models. But I would have it looked at and possibly replaced as it's hard to replicate.

Check your cam shaft mines was loose and use to do the same thing on a 1999 maxima or the crank sensors

is it random when it dies or does it die when you turn or brake or step on the gas? will it always start back up ? does it idle smooth or will it die when Idling? . is it throwing any codes on the obdII?

Thanks for your reply. It is very random. Mostly when you go to put on the brake to stop at lights or intersections or when you take your foot off the accelerator to break, and yes sometime when I turn the corner. Idles smooth but then if it is idling a little while will also die. No codes and the odometer is going blank as well.

Also consider an obstructed "idle air control valve". This can get clogged in an older engine, and needs to be cleaned. It controls the air at idle. When accelerating, the engine will get lots of fuel and air, but at idle this valve helps to adjust the amount of air. Engines will usually start and operate at idle, but shifting into forward or reverse at idle will cause it to stall. Same happens when letting off the throttle while stopping, or turning a corner. There are ways to test if this is the problem, and get it cleaned out.
Ample use of carb cleaner can often open up the port enough to help with diagnosis. Do some searches on YouTube for this valve, how to diagnosis and clean it.

The engine produces vacuum (manifold) which is used by many of the controls under the hood. If there are sizable leaks, these controls don't work properly, and can cause all sorts of problems.
So, check all of the rubber vacuum hoses where they are connected. For an older vehicle like a 98, the hoses are brittle and most likely are loose or cracked.
Listen carefully under the hood for a vacuum leak, a trained ear can pick it out. But visually check and wiggle each connection. You can try to spray the rubber hose connections with carb cleaner. If there is a leak, the carb cleaner will be sucked into the intake, and can choke the engine(too rich). So spraying near suspected leaks can help to locate them as well, because the fuel air ratio becomes too rich, and the engine does not expect this.

Thanks for all your help. My mechanic says he has checked all the rubber vacuum hoses and the air control valve........so I don't think it is this. Wondering now if the system ground is buggered up with corrosion.
