I have an 02 with an edge juice with attititude. Last week the truck died on me several times while idleing. No rough running and then die, it was just like someone turned the key off. Every time it did this it started right back up, but the attitude would not turn on (display was blank). The truck has done this about 7 or 8 times now and did ot once while driving down the interstate, but the other timnes were all at idle. Any ideas? I am thinking maybe something wrong with the edge because every time it happens the display goes blank and even when I restart it stays blank. After a couple of shutdown and starts the display starts working again.

It is for sure the edge that is doing it. Me and my buddy both have the same edge with attitude and it has happened to both of our trucks more than once. Dont know of a fix for it yet. Does not seem to matter what updated version you have of the juice either. Let me no if you here of anything and I will do the same.
My truck is an 01 and my buddies an 04. Does not seem to be a truck year specific problem.

Try unplugging your edge as this was what caused mine to die at a couple of lights and finally while pulling my 5er it died in the middle of the hwy. Unplugged it and it runs just fine. Called edge and they are sending another replacement. They are supposed to have a fix for the processor in a month or so. This will be my third unit..Good Luck
