Pulling a boat up a grade in the highway. Suburban suddenly lose power. I merge to the shoulder the engine sputters and dies. Tried to start several times sounded like the engine was flooded. After a few minutes Car started in normal condition. Hopped back into the freeway half hour passes again up into the grade about halfway or 1/2 mile she lost power again. Did a couple more time until I got home drove over 180 miles. Without the boat she runs perfect. What could be causing this?
