Please help me figure out this fuel issue! Could it be the APS or APP

What is your question?

Ok my Toyota Sequoia started having issues. The truck would crank with starter fluid but once I am going it would lose acceleration and i couldn't press the pedal to make it go. I would let off gas and then ease back on to pedal and it would go again. Now it wont crank at all after changing the fuel pump, fuel regulator, throttle body and checking all the lines for leaks and also replacing o rings. I am at my wits end and also the end of the pocket book! Can someone PLEASE HELP ME!

What makes this problem better or worse?

after it sits for an hour
