Try bleeding the rad there might be some air in the system, I've heard that this can send mixed temperature signals to the ecu, there's a bleed screw on the right hand side of the block where the pipe from the rad joins into the block, try bleed that first but its not the highest point in the system, you might have to try something like this http://www.driftireland.com/showthread.php?t=10326&highlight=bleeding

Have a look at your distributor timing. check is set to factory spec.

more than lightly its your coolant tempreture sensor,its failing when shes hot so its putting ur ecu on limp mode !!!!!!!!!

Probably a temp sensor
