The first to fall was Marco Andretti, whom stalled his No. 27 on Lap 14 and cited a sensor issue as the culprit. Then came contender Alexander Rossi whom suffered an obvious engine failure on his No. 98 on Lap 62 from inside the top-5.
Takuma Sato was running outside of the top-10 when his No. 26 inexplicably lost power on Lap 78. Finally, Ryan Hunter-Reay was running second to eventual winner James Hinchcliffe when he too stalled his No. 28 with five laps to go.
