... You definetly have a poor connection somewhere,...and it's either arcing in a box somewhere or at the panel...Check your panel conductors..Neutrals especially..is there oxidation in the panel,at the neutral bar??... if the neutrals are corroded,you're likely to have a bad connection (high impedance),and the more the circuit is loaded,the more heat and arcing build up,...it'll be a good place to check.. Good Luck,let us know how you make out,..I'm sure we'd all be interested..I know I am..
