Can someone please help.

 

Check and clean your iacv... That maybe the problem.

 

Check your gas lines? did you take the whole fuel pump out an check it out? strainer bag may need to be replaced.. maybe even bad fuel filter..

 

Engine in the car?

Any CEL?

Check fuel filter and FPR.

 

Check your grounds. It honestly sounds like you're just shorting out, or the circuit is being broken at the main relay, so that would be my first point of digging, by checking the grounds to everything.
