Question about Oldsmobile Bravada
starter is bad, (if it spins up fast and the crank shaft is stalled its a bad starter (battery charged 100% and good)
problem 2 is called low idle and will cause stalling
there are vast ways to stall any engine, (i will not list them)
1: egr stuck open , stalls at all stop signs.
2: isc stuck closed,
the former is harder to save the stall with right foot actions?
the later is childs play, (you are now an ISC)
that starter can in fact fail in many away.
Shorted (over current and causes solenoid to drop out)
open, starter, its dead as a door nail.
bad solenoid. causes free running of starter, it spins up real fast
and the engine crankshaft is no moving,
this is a bad solenoid or just a dirty shaft for pinion.
solenoid main contacter, bad, intermittent starts. or DEAD.
the contactor can sieze, and engine keeps cranking
this is a horrible ugly mode of fail, the engine can infact
destroy the starter (100HP kills 5ph starter by going over speed.)
theres is a clutch in the starter that prevents this, but it to can fail
or get dirty and jam.
if you were to say exactly what the starter did,. step by step
we can answer the why>?
i turn key, the starter spins ,but not engine
or same and its too slow
same and it only clicks
or same and when i release the key the starter is still making noises...

is this car still under warranty? if so take it back to the dealer and don't accept it as repaired till you drive it. sounds like the logic that controls the transmission is flipping out, sometimes they will tell you that it needs a reflash. what this amounts to is that the manufacturer put some not so great programming in the logic when they built the car but now they have a patch or fix that makes it work better but you have to pay them for their time to install the fix. ask them what they will charge you for the privilege and decide if it's worth it to you. there is a recorded technical service bulletin about harsh shifts for your car. well, actually there are two, the latest one a revision of the first. i would try to make this their problem, it really is. hope this helps.

your camshaft position sensor may be going bad. usually with an old car it tend to go bad. The top of sensor can be covered or gumed up with grease, oil, dirt and cause it not to detect the flywheel turning. Camshaft sensor send single to your DME to deliver fuel and sparks to you engine. If camshaft sensor goes bad it will seem like your fuel pump and ignition coil is bad even-though they are good. Faulty camshaft sensor may caused you to have this issue and problems such as sometime it run good and all of sudden it shut off, sometime its start good and others time is doesn't start. Once the sensor goes bad, the car will not run. There are two Sensor one for the fuel and one for the sparks, I would replace both sensor because soon or later if it will go bad, it will leave you stranded although if you replace one you might as well replace the other. Check the coil and test using the light or volts tester to see you getting power to the coil, next check if your fuel pump is working, fuel pump will not stay running unless the sensor sense the flywheel is turning from your camshaft sensor. next time when your car does not start, check if you getting spark and fuel. Both sensor will cost you around 130 bucks. assuming your DME, fuel pump, coil, wires, etc... is working. keep me update and I will try to walk you through. btw stop by at any auto part store and pick yourself up Haynes auto repair book for your car, its a great tools and investment to have for your next repair work if you plan to keep your car and get to know the heart of it. good luck and i hope that help some.

Could be a fuel pump that is going bad. Some times when fuel pumps go bad they cavitate and pump not just gas but also air. If you get too much air in the line and not enough gas the car won't start. Have a mechanic check your fuel line pressure.

SOURCE: bmw 325i 2003 stall
Sounds like you have a small bit of dirt or grit in the fuel system when accelerating it is drawn with enough force to cut off the fuel supply then is released when engine at Idle.
1 run liquid fuel line/injector cleaner in 1 tank
2 check fuel lines for debris
3 change fuel filters
4 have fuel tank flushed
here is trouble shooting order less expense to greater.
