Sniper EFI

Ok so have the sniper efi it’s been on for a minute does not control ignition. I’ve been running into an issue with it. The other day was driving no issues what so ever stopped turned car off for maybe a minute then it wouldn’t start. Found out the injectors were t squirting any gas on start up. Poured a little gas down the throttle body and boom she started up all day no issues. Started up everytime no issues. The next day did the same thing. Put a little fuel down throttle body she started tan it the rest of the day no issues. Has anyone had this issue before and if so how’d you fix it? I e had this system on the car for about a year. Changed nothing and it it’s done it twice in two days.
