Car dies once warmed up!!!

Just fitted a new engine about 2000 miles ago with bigger turbo's, pistons, intercoolers and injectors and running it in on a 555 chip until i can get my aem ecu mapped up. Everything was running fine until last night when i broke down! The car would turn over but not start until it had cooled down then once warmed up again it would die. i noticed the wiring harness going to the knock sensor was damaged so i repaired it but the car still cuts out once warmed up. Any suggestions would be appreciated

    ptu is the most common cause and is renound for this exact problem try a known working one if it is the case get a series 2 ptu they have never known to fail.

    Certainly sounds like the PTU. Do a quick search for PTU and all will be revieled ;)

    PTU - You'd have to drop 3 or 4 coilpacks at the same time to make the engine die ;)
