What you see may dictate your next steps.

I agree with recent remarks that you may have dirty gasoline.

Already checked. In both filters, the gasoline are clean as well as in the fuel rail.

So I do, perform all the sub-points as advised above.
I just went to the craiglist and find an advertisement for the sale of a jaguar in Sacramento, my friends live nearby and an hour later they were already watching the car. Friends said that a very good condition, the next morning I bought the car)
The former owner sold the car to the junkyard just two weeks ago) several people approached me and were very surprised that the car was in such a condition at the junkyard. They even envied that they didnít see this jaguar before me)

This a common problem with these cars apparently.

I turned off the Fuel Injection Timing Sensor and the engine warms up and does not stall. Buy new, write the result.

I still can't believe that car came out of a scrap yard !! It is a real beauty.

You might find this of interest: -

Fuel injection and the Jaguar XJ6 4.2 Series 3 / AJ6 Engineering

Pay particular attention to the known fault within the AFM of the two very small contacts that maintain voltage to the fuel pump relay. Your car seems to have the same symptoms I had on mine, namely a sudden and unannounced shutdown of the engine, (and in very embarrassing situations too,like poo on the seat stuff when overtaking !!)

It's San Francisco, Jim, they throw away some of the Most Incredibly neat things!

I agree though, this is the Nicest car I've ever seen in a junk yard, even just out the door that they hope to sell to some unsuspecting sucker. Good Score!!

That sensor is called the Thermotime switch. It is part of the cold starting system, and controls the feed to the cold start injector..
I'm not sure how unplugging it would help the stalling issue.. Maybe it was stuck open and you had a constant flow of fuel into the intake? Perhaps you were overfueling??
I hope it's the issue..

Another thought about the fuel pump...
I had one that would read a perfect 34-36 psi at the rail at idle...
When it was under load it would drop way down, eventually stalling out the car.
The way I figured it out was to run a long fuel line from the fuel rail (where the cold start injector line is) to the windscreen, with a pressure regulator where I could see it going down the road. Replacing the fuel pump solved that issue... may be something to check out...

I want to replace the sensor and then lengthen the adapter on the pressure sensor to see the fuel pressure while driving. it's easy

That's the Bosch number, you'll have better luck searching by the Jaguar part number EAC1385...
Full disclosure, this is my site, but here is a link...
https://shop.everydayxj.com/XJ6_Ther...13-eac1385.htm
If you pull it out to test, you should be some resistance (seems like 50 ohms or so, I think) between one of the pins and the bottom of the switch, and also between the two pins. On the other pin and the bottom of the switch you'll have an open circuit... When the sensor is cool..
Those values will change when the sensor heats up...
But, if it's calling for full time spray from the cold start injector, it's just as easy to confirm that being the running problem by blocking off the fuel line to the cold start injector....
It's just tough to figure out how that could be an intermittent running problem, that would go away with a stop and restart....

I saw two of the same jaguar at the junkyard , I will try to remove this sensor there in the hope that one of them works.

I replaced this sensor, started the engine. The engine worked for an hour. I drove about 10 miles to work, stopped the engine. After 20 minutes the engine will not start again until it cools
hmmmm🤔

What yard are you going to? If you don't mind me asking.

Question

I thought that the reference to an SF yard was odd. But, by implication, it seems that the yard is in Sacto. I think it might be Rancho Cordova. As I recall there are at least two there. Years ago, my lump's "kit" came from one.

Some means of an on line search???

Carl..

"I replaced this sensor, started the engine. The engine worked for an hour. I drove about 10 miles to work, stopped the engine. After 20 minutes the engine will not start again until it cools"

Have you ever lifted the fuel caps and check to make sure fuel is being returned to the proper tanks?
Thinking you may have a bad return valve going to one or both of the tanks...
Thought of grabbing one of the ignition amplifiers from one of those parts cars? That may help, too.....
