I have a 2002 chevy suburban w a 5.3. When I'm driving i give it gas n it boggs n doesn't go. If i either shut it off or put in nuetral n shut off it seems to reset n takes thrittle again. I had to do this multiple times on the way to work today. I just replaced fuel pump like 8 months ago and replaced fuel filter like 2 months ago. Any help would be appreciated.
