I have the same problem with my AGU, if i use Iridium or PFR6Q plugs, But if i use the standard plug BKUR6ET-10 its fine, and they have never let me down.

use BKR7E NGK copper plugs gapped to around 0.28

change every 5k miles with oil change

Perhaps try a range colder on the plug or tighten the gap on them. Or do both.
