P3190-Poor engine power and P0A0F-Engine failed to start

Working on a 2006 Prius. Keep getting these codes intermittently. One day drives perfect 46 mpg. The next engine turns over 15 seconds but doesn’t start. Sometimes if attempting to drive battery drains and red triangle comes on among other lights and will not drive unless codes are cleared. Did manage to keep it running while spraying brake clean through throttle body. Has rebuilt battery, new fuel tank assembly, clean MAF and throttle body. New with these cars and any help is appreciated.
