In looking over your posts , I couldn`t find anything about what your plugs` condition is .... do they read rich , lean , fried or what ?? Also , what are they gapped at ? If too wide , the engine will breakdown under load .
Are you running an MSD ... they are very sensitive to low voltage . You mentioned the PV being new .... doesn`t mean it isn`t bad as I just went through that . You might try replacing them after reading the plugs .
Good luck .
