FORD 500 FUEL RAIL PROBLEM

2005 Ford 500 • 90,000 miles

Car dies while driving. Error code 191 - fuel rail. I followed TSB 07-4-7 to trouble shoot, replaced some parts based on diagnostics, but did not correct problem.
I further tested each part in TSB by unplugging until car dies, plugged parts back in and the car would start, without having to turn the car completely off. This appears to be different then when I drive because when the car dies driving, I must turn to off before it will restart.
The problem is so intermittent, very difficult to repeat. Any further ideas?
