Tip-over-sensor engine stops

Hi all V-gurus!
My 2015 DL1000 has got a severe problem.
The engine stops at varying intervalls,both at low speeds,high speeds,at parking etc.
When the problem appears it will start again when I the bike slightly to one of the sides instead of standing straight up.
It seems like the engine stops due to the TOS-sensor (tip-over-sensor) shuts of the relay or something like that.
I have of course also checked the sidestand-sensor/switch but that one seems to work fine.
I have pulled the TOS-sensor apart and checked it for failures but so far it also seems fine to me,but this sensor has some small circuits on a printboard instead of the older ones.
A new sensor is ordered,but until then;
Is there any other gyro-based switches/sensors etc somewhere on the bike that may cause this problem other than the TOS placed under the seat and the sidestand-sensor/switch?

Check that the battery and ground connections are secure and clean making good contact.

Also sometimes the clutch lever switch connector becomes unseated and causes problems.

Great news,problem solved!
I cleaned both the contacts at the TOS as well as the clutch-handle,still no luck.
But by just pure coincidence while the bike stood on the sidestand with engine running,I leaned over to look deeper into the electrical department. While doing so I rested my hand at the little metal-lip supporting the front-end of the seat,and all of a sudden the engine stopped again.
Started the motor,pushed the metal-lip,and whola! The engine stopped again!
This is the first time I managed to provoke this failure controlled,all the other times it just happened following no speciffic pattern.
I then removed all the sidepanels surrounding the tank before releasing the tank it self,and found out that the electrical connectors on top of the fuelpump was mounted at such angle (in the space between the tank itself and the part where the tank meets the seat) that when pressing that metal-lip (on the outside of the tank-cover) one of the connectors got pressed against bare metal,causing the fuelpump to quit.
Problem solved,hurray!!!
