My 2004 chevy suburban ltz. When I was driving on vacation on the interstate when I would drop down to pass or go up hill the truck would shut off and loose all power I would sit for one minute start it back up and drive again. It will do this four to five times in a 200 mile trip and then drive great for 500 miles with no problem. We put new filter and cleaned air filter and the mechanic put it on computer said it is running lean and a tranny slip code is coming up. Checked fuel pump seems ok what could it be also emmision light comes on and the last time it happened it turned off
have the same problem?
