Maybe you should try changing out the engine oil and filter, if not recently done. It may be other stuffs, but this one is a good start. ;-))

ohkmd, good luck! I had a CE320 that had a similar problem. I would back it out of the garage drive about 100- feet up the street, bang "limp home". I'd pull over stop and restart the car and never have the problem again until the next morning. Tried every suggestion under the sun, had the ETA rebuilt, new wiring, new speed sensors, etc. You name it, we tried it. Finally sold the car to my mechanic who is still driving it with the same problem. A real mystery.
