Message I think you should verify what plug you have.

Verify the gap.

Wrong heat range, plugs gapped not tight enough, and shitty fuel can cause the problem you describe.

Of course, other nasty things can cause this too. But those are the usual suspects. If the car has been detonating, and you've damaged (pitted) the inside of the head, or heat melts the edge of the pistons - then no matter what you do with plugs, gap and fuel, it'll still behave badly and it essentially feels quite similar to spark blowout. Only, it's much worse of a problem.
