Engine #2 power loss during take off roll

[CubanPete 0]

Hello!I searched for the problem I have, but I didn't find a topic.Here's my problem: sometimes during take off roll the engine #2 looses power and goes back to idle. It happens usualy approximately 10 secs before v1. A/T is on, TO/GA is active, FMC is setup correctly. No failures are active, no warnings in the cockpit. With a small movement on the thrustlever I can "restore" the take off thrust. I use the saitek yoke system but had the same problem with my old logitek joystick.Has anybody a similar issue?

do you have any other device linked to your computer that could send commands like z-axis to zero

i have only connected the yoke with the quadrant and the saitek pedals, but as i had the same issue with my logitech joystick the pedals were not connect.
