Why does my engine die when I engage the Electric Clutch?

I have a Husqvarna YTH2348 and every time I try to engage the Electric Clutch/PTO the engines dies. I've replaced the clutch with a new one. I have also even tried to engage the EC PTO with the clutch itself unplugged. The engine still dies (nothing wrong with motor). The Brake Safety Switch works (because the engine starts) Ive bypassed the seat safety switch (engine still dies when EC PTO is pulled out to engage)...I only know something is killing the engine when I pull the PTO knob out to engage the clutch...............HELP!
