1994_GSR_ACURA

I have a 1994 gsr with a B20B block gsr head and tranny, I've used the car about 4 months since I bought it and then one day it start stop acceleration so I had to turn it completly off and then on to continue on. Later the car would take me to work but on my way out it don't start. After a few tries it will start. I've changed the fuel filters, sparks, coil and main relay and it still with the same problem, now it got worse, no when it doesn't start it doesn't start that's it. Please if anybody can help out here I'll appreciated. Thanks
