vt v6 braking down under load

[hessianracing]

when you load it up or step on it it seems to brake down (lose power)
any help

I'm no mechanic but maybe it's a blocked fuel pump? Dead/dodgy spark plugs or leads?

My LS1 was doing this after me being a ******** and not buyn leads, I borrwed some off a mate through them in and stop and runs good as new now... there not that dear for a v6 i think maybe $50 odd ? and get plugs while ur at it. coz i did plugs 1st and it stoped it for a day then came back b4 putting leads on.
