no power to dual pump system

[aafc]

I have a strange trouble, went to start car and no fuel pressure ( now this
happened with the dual system and single pump system). Checked the
connector at the tank no power, I then went the the FP1 fuse no power.
Ok but I wait for a few minutes turn key and I have fuel pressure and car
starts and runs fine.
I'am I missing something? also checked for trouble codes , no codes.
This is as far I have gone in trouble shooting. I have tech 1A
