Should get up to 4000-4400 RPM but can not get over 3400 at full throttle. After about 2-3 minutes at 3400 RPM both engines power back to about 2200 RPM and will not get on a plane at either 3400 or 2200. What could cause both engines to power down? And what would cause it to not get up to full speed (4000-4400 RPM)?
