Missfiring under load??????

[slick_red_VN]

Can anyone shed some light on my situation.

Only happens after turning a corner or a roundabout but not always.
When i put the foot down it will kick back take off but all of a sudden it hesitates and miss fires for a second or two.
Thought it could have been my dfi and coil packs after i changed the plugs and leads. After replacing the dfi and coil packs it is continuing to do it.
Wondered if it was just when my fuel was low but filled it yesterday and it still happened. Could the fuel pump be giving way?
Or maybe even the ignition module or my ECU.
I havent checked my codes yet but the engine light doesnt come on at all

Anyone experienced this before?
Has happened in my old vn but the dfi and coil packs fixed it

Could be spark plugs breaking down under heavy load could also be a crossfire from HT leads or dodgy leads letting go under light load

its got new plugs leads coils and dfi i am thinking the fuel pressure regulator diaphram could be giving way or the fuel pump itself is cutting in and under under heavy load but it doesn't always happen
