Anyone have problem with edge 540 with power meter connectivity?

Hi. 

I bought edge 540 solar recently. When I go out, my edge 540 constantly misleads my stages power meter. It drops the PM signal  likes every 5 min, and it shows 1-2 sec of 1500w when I ride normally 160w cruising . 

Since I have used my PM with wahoo roam more than 4 years, it was never happended - and still my wahoo is working perfectly with my stages PM. 

anyone has same problem with me? Anyone fixed it?  
I am so much frustrated for the new GE540. I will never buy any of garmin product again.
