2006 Toyota Other Starting

Car has to be cranked 4 to 5 times before it will start in the morning. It will then run fine but many times it will be difficult to start after engine is shut down - after driving for many miles or hours - and attempt made to start it again. Checks were made on fuel pump and found to be OK - confirmed by the fact that vehicle will run at high speeds and able to go up-hill easily.
Engine check light does not come on.
This 'non-starting' occurs at random.
