Unfortunately Nissan has not been able to find the exact cause of this problem. If you take the vehicle to the dealer, they change parts that they GUESS is the problem, people had spent thousands of dollars and still have the same problem. Some technicians say that a recall is on the way to fix this problem, but as far as I know, they haven't even found the cause, so until then, keep checking with your dealer. On every Nissan forum you'll find people complaining about the same problem. Here are a couple of complains.
1. My dealer told me it was because of low brake fluid causing a sensor to activate the "fail safe mode" signal to the engine. This was the first time (c.25,000 miles)
The second time the same symptom occurred and my dealer replaced the catalytic converters (c.50,000 miles)
The third time the dealer said it was a fuel system sensor and the part would cost $324.00, plus labor. At the same time I was told that a part of the steering system must be replaced at a part cost of over $1,100.00.
Not one time has a warning light come on.

2. The dealer said this resulted from the brake fluid being low. He replaced the brake warning light ever came on for low brake fluid, or anything else.
At around 50,000 miles the engine failed again, just like before. Dealer said it was because catalytic converters were clogged. He replaced them and I went on my way.
At around 70,000 miles the engine failed AGAIN the same way. Dealer service manager said it was a fuel system sensor of some kind. He insisted this was because the air cleaner element was not a Nissan brand and would allow dirt to foul the sensor. He suggested replacing the sensor..cost $324. At the same time he said there was a steering system part that needed to be replaced..cost $1,100+.

The engine and transmission in this cars drivetrain are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s)

1998 4 runner limited looses power after driving for two hours

Check your gas cap to make sure you let it click a few times when tightening it. It can actually make the system go all freaky. The Check engine light will come on with a bad gas cap. I will do some checking and get back to you also. Good Luck

1996 oldsmobile lose power atfer it reach 25mph the low traction

Per your description, it sounds as though there may be a wheel speed sensor problem or a tire that is low on air pressure.
The traction control system on your vehicle relies on four wheel speeds to determine if the vehicle is in a skid or not. If the traction control system sees one of the wheel speeds lower or higher than the rest, it thinks your in a spin or skid and will reduce power to compensate and straighten the vehicle.
So, first thing to do is check all four tires and make sure they are at the same inflation rate some where between 28 and 32 lbs.
Next, disconnect the negative battery cable for 5 minutes, this will clear the module and let you start fresh.
Try that first before any parts are replaced.
Good luck and let me know.

Check your intake and exhaust modules. I have a 1987 D21 and had the same problem (if I understand your post). I replaced the modules located behind the driver side headlights and it fixed the problem. Good luck! I hope this helps.
