I would guess a sensor. Do you have any bad codes?

SOURCE: my bmw 328i misfire?

If u don't have a check engine light try this procedure to fix it.
Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: BMW 2001 X5 stalls out

Hello there

You MAF sensor (Mass Air Flow) is dirty and most likely on its way out. The next time this happens just unhook the connector and you should be able to drive the car in safe mode.

Hope this helps. Please don't forget to rate me.

check the starter

at the engine, there is a small sensor that helps increase or decrease the rpm of the engine. Perhaps yours is soo low, that when you slow down, it's almost about to stop.

The other problem could be the airfilter sensor. If it's not properly fixed or if the sensor itself is a bit damaged, than the engine is not getting enough air and so, let's the engine almost go off.

Please give further details if this has not helped.

thank you

SOURCE: Car hesitates/stalls when engine is warm and car starts to move.

Sounds like a bad motor mount, pop the hood and see if the motor shakes or moves rapidly when u put it in gear holding down the brake.

After driving 20-30 minutes I shut the truck off and it will start but then dies and wont start again for 40- to a hour

I have a similar problem. My engine shuts down after about five minutes..
Measuring the current into the distributor(ignition) reveals a jump in current from 3 to 40 amps.
The power lead is red on white and the ignition lead is yellow on black and goes into a connector under the dash where the ignition wire changes to white on black. Three different wiring diagrams give no clue to how this problem is caused.
Also, the starter is good for only a few turns after the engine warms up.

It sounds more like the pump, if the converter fails it would have a crazy lock up shifting problem. Sometimes the bearing for the torque converter will loosen and spin in the housing this to could be the issue.

1995 bmw 3251 hard to start after warm up sometimes the hazrd light will come on when it wont start let it sit for a couple hours start right up run perferct when driving

I have this very same problem. When i try to start ot after it warms up i just get a wirling sound. After about 2 hours when it has cooled down it will start fine. The problem is the starter motor. The solinoids exspand when hot and lose contact because of the heat fom the engine. This is a classic starter motor problem when they are on their last legs. The only other thing it could be is the brushes loosing contact. Either way just replace the starter and it will be fine.

Sometimes start up with only five celenders.

try checking your plug wires or just changing them... if you can get a test done to c which cylinder isn't firing, try changing the coils or coil pack (whichever a bmw has)
