Car wont accelerate/Rev But idles fine

Okay, so Friday I put $20.00 about fifteen gallons drove around town then headed home about thirty miles total with no problem. Saturday morning cranked car started to leave my drive way and noticed something was not right was jerking when accelerated so put in park car would not rev past 2000 rpm's, so I figured MAF sensor or TPS. I replaced both still same problem. Car will idle fine just wont rev past 2000 rpm's so I let it idle for about twenty minutes and tried again car would not rev it choked and died so it seems after car is warm has more problems revving. Replaced fuel filter same problem left line off out side of filter gas is pumping out fine when turning key over so thought maybe got bad gas some how added fuel stabilizer did not help. Took off due line at fuel rail got gas all the way there. Took out fuel regulator and noticed on the fuel rail gas started bubbling up for about thirty seconds is that normal? Any ideas wont could be causing this?
