Alan,
	You are describing the exact scenario preceding the demise of DME on
my '89 325i. 
	The engine would stumble/cut-out/die and then restart on the
highway. I crawled all over the car with a voltmeter, replaced the
main/fuel/02 relays, etc all to get stranded on a cold and rainy November
night last year. The DME has finally given up the ghost - the fuel injectors
were firing randomly.
	A replacement DME will be around $200 from Roundel advertising junk
(used parts;) yards.

	That doesn't sound right since reading this code would mean watching
the light blink once - pause - 19 times - pause - 17 times - pause - 56
times - long pause. 
	Either way, if you choose not to replace the DME right away, I would
buy a spare and carry it in your glove box. Beats getting your car towed and
searching for a cab in a middle of nowhere. 

good luck,
alex
