Narrative:

During takeoff roll; the throttles split during engine run-up. I attempted to match the throttles by pushing up number 1 throttle when the auto throttles disconnected. I initially thought that I may have inadvertently hit the auto-throttles disconnect on the left throttle. We rejected takeoff at approximately 80-90 KTS and cleared the runway. After completing the rejected takeoff checklist and after landing checklist; we called maintenance control and the duty officer concerning the reject. Maintenance advised us to attempt another takeoff and the duty officer advised us to fill out a safety report for the rejected takeoff. We reconfigured the aircraft in accordance with the checklist; and completed all checklist to perform another takeoff. During the second attempted takeoff; we rejected again. During run-up of the engines; the auto-throttles lever kicked off and the ECAM warning initiated. We rejected again; ran the rejected takeoff checklist; after landing checklist; then initiated the maintenance process. The auto-throttles were inoperative and we had to make a non-profile takeoff and departure.system malfunction caused the auto-throttles to malfunction during takeoff roll. The auto-throttles would disconnect during engine run up for takeoff resulting in a reject and a non-profile takeoff after the MEL was complied with.

Title: A-300 Captain rejected the takeoff when the auto-throttles were disconnected. Thinking that he had inadvertently hit the disconnect switch; and after consultation with maintenance control; he attempted another takeoff with the same result. Engine run-up detected an ECAM warning for a malfunctioning auto-throttle system.
