S500 Trunk issue

Folks,

Have a 2003 S500 with a weird thing happening with trunk door. Sometimes the trunk does not open with the latch underneath it if the car is unlocked and when I open it with the blade key and shut it, the door opens suddenly when I drive. I guess it happens when one of the doors is open and someone tries to open the trunk with the latch. Is there a relay or a fuse issue that may be causing this?
Believe me, it gets very embarrassing to deal with it at the mall or someplace in the public. It sometime gets extremely hard to open the door even with the blade key because it does not offer any space on it to hold it.

Appreciate it.

Vish

Another thing to add was that I replaced the PSE pump six months ago because it was broken. All the doors are opening now with the fob except for one which opens with a delay. Don't know why. Would that have anything to do with the trunk lid? I have checked all the fuses and replaced all of them.
