 I'm not sure what the problem was, but I'm quite sure that this was NOT it.
There is so little "squish" area between the head and piston on a diesel
that it takes a very small amount of water to hydrolock one. This is a bad
thing. If it happens at idle, you might get lucky and not damage anything,
but at speed it has been known to bend rods and other nasty things. Probably
about on par with losing the timing belt as far as destruction goes.

 It sounds to me as though you might have got a slug of water in the fuel
(also not a good thing for the pump) or you have a loose connection on the
injection pump stop solenoid. If it continues to bother, you could
temporarily hook up a test light in the car powered off of the stop solenoid
terminal to see if it is intermittently losing power.
 Perhaps something is blocking off your intake? Did a bag or something get
sucked into the intake pipe and is now covering the air filter?
