Mysterious Decoupling

Ok -- I am stumped and could use some help from the community.

I am running a V3 with a newer HE280.

I have a decoupling error arising from my nozzle.

When I set a target temp (that is more that about 20 degrees above current temp) it faults to DEF, and I consistently get the decoupling message.

However, If I walk my temp up slowly targeting about 10-15 degrees with every target increase -- my system does not DEF. can run a print after I walk up the temp this way; but I do sometimes have failing prints mid way due to DEF errors.

First things first, I believe my thermistors are a-ok. I purchased a brand new HE280 and plugged it in have had the same issue with the new one as I did with my old one. I am suspecting I MAY have a problem with my whip, and am planning to swap it out.

When PID auto-tune ( running M303 P0 S235 X0 ) it does not DEF out.

Any ideas
