    Every now and then, engine will cut out like it is running out of gas, no KR or anything like that when it happens. Also, when i start engine when its cold, it fires right up, after its been started once and warm, it sometimes just kinda falls into a start. Think i got a loose pick up on my fuel pump??

    When you say 'cuts out' does the engine actually die, or does it just act like it's trying to die? And when does this occur, at idle, or in gear, if so, what speed?

    it acts like an air bubble got sucked through the fuel line. it just cuts out. does not die. it can be at light throttle or under load. I did a WOT it does not do it at a specific rev range.

    Might want to check the ignition module connector terminals. I have seen a fair amount of the harnesses pulled to tight and causes terminals to get loose.

    I will check those. I just installed zzp 10.5 wires. maybe they need dielectric grease.
