Losing power when using up/down on foot switch

I’ve replaced the beat buddy foot switch KERCHUNK buttons with soft push switches. I have the switches set up for song advance up/down. When I press the switch to advance, I lose power to the main unit. This happens more when I’m advancing fast or many songs ahead. It HAS done it after 2 or 3 pushes. I didn’t see any diodes when I replaced the switches, unless they were built into the old ones. Any ideas on what my problem is?
