Printer crashing after few minutes

Hi,A few year ago, I purchased a Zonestar P802QR2, which has been working fine. I usually print using Octoprint on raspberrypi connected via USB cable on the printer (working fine also).Yesterday, I started facing a problem when printing.After a few minutes of printing (which look ok), I start hearing a weird noise (as if something was blocking some mechanics) and only the Y axis (ie the bed) moves, going back and forth. The X (the head), does not move anymore (despite it should based on gcode) : you can view and hear in this video https://1drv.ms/v/c/b52ee1d684330716...AeJ6rxBH4-1TpQ . I don't see any error in Octopi terminal (cf end of the short video )If I pause the print, I can still hear a weird noise (though the bed doesn't move anymore).If I stop the print, the noise stops and I could restart a print (but a few minutes later, same problem occurs).If I stop the print, shutdown the printer, (disconnect also the USB cable to raspberry pi), power on again immediately (without letting the bed and nozzle getting cold) (and reconnect USB cable), I can restart a print, but same error few minutes later (typically 5-10 minutes).I tried to let the print getting cold again, but same error after another attempt.I tried to touch the various cables and connectors when the noise was heard, but it did not stop. I tried to fix again connectors also.I don't think the printer gets warm, as it's open and temperature room is approx 20°C (the first problem after 19 minutes of printing, so quite a short time compared to printings I could did in the past.I also tried an autonomous print without Octoprint bu using the STL file on the SDCard of the printer.. Same problem.The printer board is a Zonestar ZRIB v2.2 .Could you help me to understand what's going wrong and how to fix it ?
