I have a gmc 7.4 liter suburban when I start in the morning

Customer Question

I have a gmc 7.4 liter suburban when I start in the morning it starts right up but after it sits a little bit after driving it's like I got to prime the fuel by turning over the key on and off 3 or 4 times to get it to start. I changed fuel filter and put a Bosch fuel pump in it too. Once it starts it runs ands sounds awesome. Not sure what problem could be. I did notice when I put new fuel filter on it had rusty fuel coming out.
