It could be either the internal pickup is coming unglued or the electrical connections need to be re-soldered. If you're not familiar with the process, have it done by a repair shop. You risk causing more damage if you're not careful.
This could be caused by a number of things.
1) Socket on DD55 could be broken
2) Cable could be broken
3) Plug at end of cable could be broken
4) Switch in foot unit could be broken
Eliminate each by working through 1 - 4 using a multimeter and then repair accordingly once you have found the fault.
I assume you are using a Mac or similar Apple product. you may need to go the chooser to select the DD55 if the system does not recognize it automatically. If it does not appear as a choice you need to install/reinstall the driver.
Check that you don't have MIDI echo on in the DAW. If the MIDI data is echoed, it MAY be merging with the outgoing and when MIDI signals are merged in pieces instead of whole messages the data is corrupted. If you can look at the data stream with software, you should be able to spot the problem. Another problem might be excessive latency of the recording software. Make sure you do not have antivirus or antispyware programs running or network running. The Roland will spill data at much less rate and while the dd55 may overrun the DAW the Roland might not be able to. The key to the problem is to analyze the MIDI data stream that is being recorded.
Whatever is the problem is probably vibration sensitive. The adpater connections are notorious and you would have to use test equipment to verify they are OK. Looking at them you cannot verify they are OK. Try to see if the display blinks right before it stops. If it isn't the connections, then it is possible one of the buttons is marginal and is vibrating down and restarting. Instead of complicated stuff, just do everything on one pad at a time to see if you can create the problem. Try different pads as the vibration may need to be neaar a particular point. Myself I would open the unit and inspect for loose wires etc.
Probably the battery replacement was NOT done correctly or there is a problem with the battery voltage getting to the memory.
The original message was probably the result of the unit detecting the data was corrupted due to the backup battery not maintaining the memory.
The CORRECT Lithium cell for this unit is a CR2450
This is NOT a common available cell and LIKELY the person installed a readily available one which is not working.
This cell is thicker than the commonly available cells and if the readily available was installed, it would not make contact. Open the unit and check the cell in the holder at BT1 on the board.
Here is service manual which has disassembly instructions.
