A B767-300 flight crew reported high pressure shutoff valve annunciated on EICAS during takeoff roll. Following maintenance action; they had the same problem on second takeoff attempt; and aircraft was grounded. One of the reporters cited contract maintenance as a possible factor.

Narrative:
On initial takeoff roll (max EPR) we immediately noticed a 'hpsov' (high pressure shutoff valve) [annunciation on the] EICAS at about 20-30 KTS and rejected the takeoff. We taxied clear of the runway and went to [the] run-up pad and contacted maintenance. Maintenance had us do an engine run-up to confirm proper operation of the shutoff valves. We got the proper indications during the run-up; got a new release; checked with dispatch to confirm our fuel load and taxied back out to runway. On the 2nd takeoff roll at around 60-70 KTS we got a 'right (right) hpsov' [annunciation on the] EICAS and a bleed light on the bleed air panel. Again we rejected the takeoff and cleared the runway. This time we taxied back to the gate for further troubleshooting.
