At a guess, I'd say that in the past, she happily ran up to you and said "Mommy, potty!" and you took her to the potty. And now, she doesn't say a thing, just sits there and pees.
If so, this is common and expected. The newness and excitment has worn off. Given the choice of playing with a toy or sitting in the boring bathroom waiting to pee, which do you think a child will choose? The toy, every time.
Don't give her the choice and don't expect her to be mature enough to willingly stop playing. Don't wait for her to tell you she needs to go. Don't even ask her if she has to (she'll tell you what she wishes were true... NO!). Simply tell her it is time to try. If she pees, reset your mental timer for 2 hours. If she doesn't pee, take her back in 1/2 an hour.
If you can stand the wet panties or the puddles, the ditch the pullups. They really do slow things down.
