I did this to an Evo 6 a couple of years ago, i checked everything but it all pointed to a damaged Gems ecu. I sent this away and it cost £80 to be checked but it seemed fine to Gems. In the end i paid Steve Simpson to come to me and he tracked it down to a damaged capacitor which had cut the live feed to the ecu. He ran a new switched live and all was good again. This may be worth a look, find your switched live to your ecu and see if it's still live.

Dave.
