Thanks everyone for all this great information.

        Of course, after reading all of it I’m no longer sure where to begin!  At first it seemed like most thought it was a failing Hall Sender.  then possibly a failing electrical connection.  Or maybe the temp 2nd sensor or a leaky fuel injector.

        Also, this is very hard to diagnose as it only happens after a fairly long drive and only when  the van is re started very quickly.  Luckily even a 5 minute wait is enough to get it started normally again.

My diagnostic skills are growing but limited at this point.  So, I may have to wait until the problem becomes more evident.  

Still despite the cost I’m very tempted to replace the hall sender and keep my fingers crossed that I have the solution.

So still contemplating my next action.  I don’t have any known good spares of any of the mentioned parts to try.

thanks again all and I’m keeping all this info handy as I move forward.

I had a Rabbit once that had a completely dead ignition system, due to a single bad crimp in a single relatively inaccessible plastic connector.... it was hard to reach, but surely that little wire was find, right???
