FiTech EFI system

I'm having a problem with mine, if it's been driven for awhile and all warmed up. If I pull in someplace and shut it off. Get back in after 5 minutes, it will fire right up, run for about a second and then die. Then I have to crank on it for a bit before it will start back up. Then it will run fine. Sort of annoying.
What fuel system are you running?
