Default Missing out problem need help!!!

Ok here is the problem, 3 days ago ( and only when hot) I have in 5th gear doing like 40 and i went to speed up (AC ON) and the car just started cutting out. I went to take off from the next light and the car wanted to die so i feathered the gas and finally it picked up fine. I shut the ac off and had no problem. turned it back and went to take off same problem starts spitting and sputtering wanting to die. It has a new opti, and taylor wires with about 4k on them, i put a new coil and new tr6 plugs in it today, and on the way home same thing in 5th about 45 and it now has a constant miss. So i dont know what the problem is. It might be the ingition module or the opti but I think it is a ignition problem and not fuel. Could be wrong though, I have never had anything act like this before.

Any ideas would be appreciated.

Thanks
James

Start with a fuel pressure test. Go on from there.
