If it stops after, say, 100 yards or less, it's most likely just some damp that's got under the alternator belt. On our C900s (1987 and 1989), the alternator belt can be tightened by simply tightening the nut on the swing arm. Locate the brake booster on the LHS of the engine bay, by the firewall. Look at the belt just next to it, but further towards the middle of the car. That's the one ... See the long thread and the nut? Just tighten that one a little. Better still, slacken it off, buy a new alternator belt and tighten it up, so that there is only 0.5cm "give" in the belt when pressed. HTH, good luck guys ... Come back if that's not the issue.
