4.0 swap missing bad

[slow96gt]

ok i swapped a 92 explorer 4.0 into my ranger, motor runs good, but when i first start it up in the morning i can drive almost 8 miles and its messing up, it alomost always does it around 3000rpms or higher and sometimes around 2500, its like a brick wall, it will ideal just fine and if i turn it off let it set for a couple min's it does fine back on start up but does it again in a couple of miles, i was thinking maybe its not getting enought fuel? cause when its messing up and you give it gas it acts like its running out????? im lost on this one.. alsoni only have the frame mount fuel pump wired up the one in the tanki havent yet fgured which wires do what,,

well today i changed the plug wires hoping it would fix the problem and it was no change, but i was dark and i noticed something, the plug wires are arcing bad!!!! but the are all in the factory clips not touching a thing and one wire is arcing for about six iches worht of plugwire in length? others are arcing on the vaule cover thru the factory plastic clips??? any help would be awesome and thanks in advance
