My car stalls after its been driven for over an hour, and only after i shut off the engine and turn it back on, it catches, i have to rev it a little, but then it dies after. I have to rev for a good 30 seconds until the car stays idle, alternator issue?

This is related to your idle control valve and/or throttle switch. The symtoms are:

Car won't start when hot (after15/20 minutes) or cold (parkedfor an hour)
Car stalls for no reason...
Car shakes in idle
No power

There was member who had to replaced the switch (I think) or found a loose connection on the switch after he brought back from the dealer. Dang it, can't find it but it's there!

Ok, I did more research last night and it's possible it could be your MASS CONTROL AIR FLOW sensor based on the symptoms you described. Without a scan tool it's difficult to pin point the problem. But this sensor would be a good place to start!

The BMW service said they replaced a cam sensor. I have no idea what that does, but ok, but the car seems to be working fine now.
