Default Cutting out under load

My 89 that I just bought cuts out under full throttle sometimes usually above 3500 or 4k rpm's. It doesnt do it every time its under load though. It kinda sputters like a miss or something. The car seems to idle ok and normal driving is ok. Any ideas?

What are the plugs gapped at? And what condition is the ignition system in?

Im not sure what the plugs are gapped at. I just picked up the car a week or two ago. Havent had much of a chance to look at anything. I just noticed that it doesnt do it all the time. In my old car I had a problem with the wire arcing to the header but these are all clear.
