Sudden Decelleration Stalling/Restarts

[gwbutler]

Hello All...

I know there was a thread about stalling...waiting...and restarting about a month ago.  I can't recall what the recommendations for the fixes were. Here's run-down on my symptoms:

1. ' Leave the wagon at home and go to pick up my wife, adult daughter, and groceries two weeks ago, ... on the way home I slowed down quickly in third gear to accommodate someone essentially running a stop sign...84 4ksq dies (this is a first!).  Managed to make right at intersection and coast into a parking lot.  Car sits two minutes and cranks over perfectly...  I figure this is the most weight I've ever had in the car and I must have simply over-loaded it and somehow over-heated some element.

2.  Next day (Sunday) I take it on a test ride around town...no problems!, ...cool!  I decide to take the car on an extensive ride up to Biddeford, Maine (from north-central Mass.) Car performs perfectly on the trip up.  In Saco, Maine I slow down quickly again in third-gear to let an elderly lady pull out from a parking space...and the car dies...I coast into a parking spot... wait two minutes and the car starts perfectly.  Identical situation happened again twenty minutes later.  I drove the car back to Mass, without an incident,... The next day I contacted Rod at The Parts Connection and ordered a new Bosch fuel pump to replace the one on the car as it had "buzzed" intermittently for two weeks previous to the stalling anyway (it was old when I bought the 84 4ksq five years ago).

3. I just installed the new fuel pump a couple of hours ago.  I took it for a test drive...no problem.  I decided a half-hour ago that I would take it for a more extensive test ride  (as I wanted to start taking it to work again tomorrow).  As I was accelerating (actually in third-gear again), a lady backed out of her driveway, without looking up and down the street, and I was forced to slow down quickly again...and got the same results as before....a stall.

I really don't pound on the car (184k miles), ...I can't figure-out what's causing the stalling,...any ideas folks? TIA

BTW, car has a new fuel pressure accumulator (and lines to filter/accumulator) and two new fuel filters, fresh Wix air filter and many other new parts that have been installed and working fine for months
