Kick Stand Safety Switch

[Greybeard]

Hello everyone I'm hoping to get some help as my bike has been down for a month and my mechanic has done all he can do.

First the deets.
2006 KAWA Nomad 1600 FI
60,000 Miles.

Bike starts up no problems. As soon as its put in gear it dies.
First thing Mechanic did was clean off the switch and kick stand as it was all guncked up. It worked for him for a few days he took it out on a few test drives and the bike worked great.
I went to pick it up fired it up, put it in gear and bam it died.
I left the bike with them for another two weeks. They replaced the safty switch still would not remain running.
Then another mechanic disconnected all the wiring and re connected them and it worked.
I picked up it yesterday and rode it home about 5 miles no problem.
Came out an hour later to go for a ride and guess what as soon as it is put in gear it dies.
I can restart it if its in Neutral but it will not stay running when I put it in gear.

One last thing that I thought of the other day.
Last winter when I was taking the battery out I pulled the wires out of the middle MOLEX connector. I put them back in a sealed it up with connector grease and it worked but now it doesn't. I cannot find my manual but I seem to recall that middle MOLEX connector controls the lights and safety switches.

Anyway any direction on next steps would be great.

Thank you all.
