I had the same problem but for me it was my fuel pump had went bad. The walbro one if like 80 bucks off ebay replace it with that imo

 

sounds like you're losing spark, i'm not sure what engine you have, and i don't think you are either, but your "sr13" has a bad CAS or coil, depending on ka or sr. Probably a KA with a coil issue though. check connectors on the major sensors that will contribute to spark.
