Possibly the intake air temperature sensor or the engine coolant temp sensor are stuck at full hot. The computer will schedule too little fuel--especially with the engine cold and you'll have very little power until the engine actually gets closer in temp to the stuck sensor. The engine coolant temp sensor sends signals to the computer NOT to your temperature gauge on the instrument panel. That is a different sender. So your coolant temp gauge on the instrument panel may show normal.

radiator low in water.

Check for timing belt slapping inside of cover. Should have been changed at 60,000 miles. The cover has an inspection hole. Remove plastic plug to inspect.

good day Sir, try to check the spark plugs and air filter, i hope this tips will help you.

Every 10,000 miles partial service; change engine oil and filter, air and fuel filter's, spark plug's and check brakes fluid pipes and pad's. Every 50,000 full service. partial service plus change cambelt, check gear diff and power steering oils. Owners manual or any mechanic will let you know oil grades etc.

SERVICE IT .....OIL PLUGS, AIR ,FUEL AND OIL FILTERS GET TROTTLE SENCOR AND THE MASS AIR FLOW SENCOR CHECKED

fuel pump and float

I had similar problems after getting my ECU replaced.
later i got a letter from nissan saying it was the wrong program they flashed on the ECU (think it was a maxima ECU they flashed into my sentra)
it only seemed to do it right after my car warmed up while i was slowing down (for a stop) but never cut out when i was at a complete stop.

you can call nissan to see if there are any recalls or updates for your ECU program (they should be free if there is)

if that does not work, or it cuts off while accelerating, try checking your fuel/air ratio, spark plugs, air filter, and fuel injectors. (a fuel filter can even cause cut-outs as well if it's seriously clogged, but it's usually hard to start as well)


~guest:
kinda sounds like heat problems, check to make sure your temp gauge is working and see if this helps...
- when it cuts out on you, turn key all the way off, then turn it back to full on (but don't crank) this should let you rad. fan run without cranking your car. if this causes the wait time to be shorter before you can crank it again (less than an hour) then it's most likely a temp gauge, water pump, hose or even a belt.
