maybe someone has had this problem. my 89 525i manual has started to shut off during driving. it always seems to happen right around 3000rpm after the car has reached operating temp. it does not do it all the time ,but it is always around 3000rpm, mostly in 3-4-5 gears. i do not think it is fuel as when it cuts out it is as if the ignition is disconnected. usually fuel has a gradual "dying" or loss of power before it actually stalls out. i have thought of many possible faults, but the part that puzzles me is that none of these faults would be occuring only at the 3k rpm mark. bad coil,wires,plugs,etc would be bad at any/all rpms. any help is appreciated. sorry if i left anything out
