Check your fluid level again remember it should be at the top line.

A truly way out thought, here. The security module, under the boot fuse box, is associated with correct operation of the hood, amongst other things. If it has any damp or corrosion in the circuit board, then odd things will start to happen. Have you experienced any other issues, such as door locking problems? It can’t do any harm to clean and perhaps dry it off:
1. Disconnect the battery
2 locate the module, under the fuse box
3 undo the bolts and withdraw the module
4 disconnect the module from the wiring (if I rememer right, three connectors involved)
5 open the case, then withdraw the circuit board.
6 inspect it carefully. If it is damp, allow iit to dry fully.
7 clean the underside if the board with a new toothbrush, to remove any small areas of corrosion.
8 reassemble. Reconnect the battery and re-set the windows.
It might be an idea to take antistatic precautions while you do this. I carried out the above procedure with no problems, but I don’t know whether I was just lucky -other forum members might like to comment. Security modules are very expensive, so take care.

I did a hard reset and no change.

Goodluck with that. Bear in mind that, if it does turn out to be the security module, the steps I mentioned still might not work. The alarm issue is an interesting pointer, though.
I think that what might be happening is that when you lock the car the passenger door remains unlocked - next time it happens look in the window to see the position of the latch. If this is the cause a temporary workaround is to lock the passenger door from the inside first, then leave the car and lock up. You may have to do so with the key, rather than the remote. When you unlock with the key, put it straight back to the ignition and turn on. This prevents an alarm.

I took the security module out and cleaned it. It looked in perfect condition. Put it back in and I of course have the same problem.
This issue is frustrating for me because I have taken most of this car apart, fixed and put it back together. It now runs great except for this problem which I've thrown a lot of money at. Still no love.
To recap, all hydraulic lines replaced, latch and rams redone by Top Hydraulics, fluid filled to top of line. I put the top down manually. Do a hard reset. Then when raising the roof it will get to the latch, the latch will pull the top down most of the way and then stall.
After weeks of it not working, at some point it will just start working correctly, and it may open and close 10 times without problem. Then when you least expect it, back to the same problem.

It could be an intermittent microswitch. Gus and I have developed a top tester (see https://www.jaguarforums.com/forum/x...st-box-198922/) which could be a last resort for these kinds of issues.

John,
Can you make a video (with sound) of the pump reservoir during a raise-top operation that fails in the way you described?
As our resident physicist Sabrina once pointed out to me in a PM, it's possible for a seal to be permeable to air but not to fluid. So the long-shot I have in mind is air getting in there somehow. Evidence of this we might be able to see and/or hear if you can make a video.

Yes, the pump, specifically the reservoir. Been done here before. Easy with a helper. No need to use key in door; use console rocker with engine off. Your call of course.
