not sure if this is the right area for this so feel free to move it.

I'm having a problem with my car shutting off a various times. I installed 3 255 pumps, running on e85. we tuned the car for 10 psi, car was running great. next day the car would turn off under boost. then it was turning off during normal driving. the car idles and drives fine,I cant figure out wtf is causing this. at first I thought the 3 pumps were drawing to many amps and causing the car to die. I found out my tensioner was bad, fixed that. then I thought my cut off switch was the problem (cheap one that came with a relocation kit) bypassed the switch. it doesnt seem to be happening as offten, however sometimes it will just shut off.

is this a pcm issue? or something electrical that I'm over looking.

the pumps are wired off relays and a stock singal wire. the car is running 10.3-10.8 under boost (e85), fuel pressure is steady and raising under boost. volts hold solid even when the car "hick ups". plugs look good.

I do have all my gauges wired into the stock ingition wire, key on all gauges come on. 5 gauges,one sacavge pump.

any help would be great!
