[SEL] Off Topic - Car Troubles - Buick - HELP !

Hi List,
I hate to keep coming to the SEL for help with my vehicles but I have another problem I can't solve.  
The '95 Buick Park Avenue Ultra with 67,198 miles is giving us trouble.   From a "cold" start, it starts, tries to run and dies.  Then you have to turn the key completey OFF, then restart it.  Then it MIGHT run okay.  While I'm driving, It will run okay, but then stumble a little, like the ignition is trying to disconnect, and lights flash on the dash.  If it dies, you have to drift to a stop, turn the key OFF and then restart it.  You cannot turn the key OFF until it is in PARK.  (Which is very embarrasing in traffic.)
I had two mechanics say it was the fuel pump.  A new fuel pump and $400 later, the problem persists. 
This condition has seemed to come on gradually.  After running and stopping at the grocery store, or what ever, and restarting it, it would run very rough.  But once put in gear and moved, it would run okay.  This has progressivly gotten worse.  
Another thing - - - I'm not sure if this has anythng to do with it but - - - It seems like it dies after a 90º right turn.  This has happened to me 3 times in one evening.  I can't imagine any "dangling" wires or connectors.  The car is like a new car -  immaculate and no rust.  Temperature, Rain or Sun doesn't seem to affect the problem.
When it happenes, there is a lot of instrument light flashing and - for some reason - the Ext. Temp. screen keeps blinking for about a minute after it restarts.
It does NOT have an on-board diagnostic. I don't have a reader and the mechanic that replaced the fuel pump just says everything reads fine and he can't get it to continue what it's doing.  He would have to be reading it when it dies.
I'm tending to think it's a sensor or module of some sort breaking electrical connection or smelling something or ???
HELP !!!
