I have found the problem which was causing my car to cut out when heavy on the foot, In my case it was the IPM (fusebox) ECU that is on the front, I tried cleaning all contacts aprox 49 but in the end it turned out that this unit that was faulty, I had a IPM unit in the garage with the ECU, after changing the IPM ECU took for test drive and was all okay, took for another test drive today aprox 60 mls with out a problem, so in my case it was the ECU on the front of the IPM (fusebox), i am not saying that this is the problem for all 1130 codes but in my case it was, just a signal drop for less than a second to the HP pump regulator which was enough to drop rail pressure,which the main ECU/PCM picks up on and cuts injector live feeds resulting in engine cut, that's why when you turn off ignition the main ECU resets and the cycle starts all over again, its worth checking that all terminals are clean on the IPM ECU unit, when removing pull it straight out, don't wobble from side to side 49 pins and make sure you have not bent any before putting back, hope this helps
