Note: this isn't wholly a 'bug' as, per the explanation in hl2_player.cpp, in CHL2_Player::SuitPower_RemoveDevice(const CSuitPowerDevice &device), it is said that this is a "a defense against exploits where the player could rapidly tap sprint and never run out of power".
Indeed, removing the SuitPower_Drain(device.GetDeviceDrainRate() * 0.1f); from it prevents running out of suit power when tapping the button. And it makes it easy to exploit.
Perhaps an extra check could be added there to only do that if the player isn't stationary. Or perhaps it should be left alone.
