Very bizarre situation with my 95 318i...has happened twice in last two months. I'll be driving along fine, and then go to change gears and the car will briefly (split second) loose all power (steering, radio will fuzz out for a second, guages will light), and then get it back and drive fine. The RPM's jump up during this instant too. Car doesn't die altogether, it's like it just hits some type of glitch.
I'm worried that this problem might get worse, or that it may occur during a time when it could put me in danger.
I don't think this is your alternator problem.. Although I might be wrong, I don't think the symptoms are of an alternator. Although to knock out the Alternator, I would do a check on alternator itself with a multi-tester..

jlb318 I think your problem is actually your ignition switch. What you might try is to lift your keys up and down while you are driving. Donít rotate the key because you might accidently lock the steering wheel while driving and cause a accident. But lift vertically up and down and if your glitch reoccurs then you have your problem. What prematurely wears out the ignition locks & ignition switches is the weight of a heavy key set. Meaning too many keys on the key chain. A suggestion to anybody reading if they are doing this it is better to get a quick disconnect key chain and only have the ignition key by its self when operating their vehicle.
Hope this helps
I would have to agree with fernguy. That would actually be the first place that I would look. I have seen that happen several times. If the ignition switch is not your problem then I would begin my focus towards the DME and it's connectors. The E36 has the potential to gather moisture and condensation in the cavity where the dme is stored. I have also seen connectors work themselves loose. However, I believe that you will find your problems within your ignition switch.
fernguy... are you a tech or have you just experienced this problem with your own car??

my 92 325i used to do the exact same thing, I would be driving and then all the sudden i would lose all power, then I would floor the gas then all the sudden it would kick back in and take off...In the end, all 6 of my connectors to my spark plugs were corroded badly and was also causing my car to sputter...You may want to have that checked....That fixed all my problems!

Thanks to all who have replied...the ignition switch could very well be the problem, as I've noticed other problems with that in the past, which I thought were totally separate and unrelated. For instance, sometimes when I go to start the car, I insert the key and turn it, and it doesn't catch on anything. I can literally spin the key a full revolution without starting the car.
jlb318 Now there is a difference between a ignition switch and ignition lock.The ignition switch actually is mounted directly behind the iginition lock. The ignition lock is the part that the key inserts into.And yes that is okay for the lock to spin when the key is not inserted properly it is part of the theft-deterrent feature of the car.The ignition switch is a electrical component that is mount directly behind the ignition lock that actually moves in conjunction with the lock to supply electrical service to the vehicle at a given point of its rotation. I thought I should make this point more clear.
Hope this helps.
