2009 Pete 396 problem

Hey fellows. Well I drive a truck for an o/o but it's having problems. I really don't know the exact word but let me explain the issue. Anytime I stop either fuel up, pit stop anything. Once I get going it sputters, I mean you can hear a loud buff! In the air filter. Once that happens the throttle cuts off. To me in a gas car would be like it's missing or backfiring. I'm taking it to Peterbilt the weekend after but hoping someone could shed some light thanks.
