Starting problem

[nrgotenk]

So yesterday after a long time cruising on highway, enjoying evo I went back to the city, everything was great until I stalled at the light, I was lucky it was 1:30am no cars around, I couldn't get the car to start, I can hear the pump, and nothing more, after couple tries I opened the hood to check out if something is happening there, touched some wires near ignition (HKS dual) tried to start nothing happened, waited for another 3-5min and gave it another try and it worked, turned it off and gave it another try it worked again, so I'm driving back home a long drive ~30min, and I stall again (stupid Triple clutch) this time same crap but took longer to start again. What can it be???
