We check the grounds , even added another ground same problem.
The fuse is not getting hot.
Had Hyster come out they don't even know. He replace diaphragm in carb which was already done , but still same problem. Sometime you can get a nice high rpm than it dies out. But will start back up right away. Or at times won't start up. Wait 20mn starts right up runs than dies out. One thing for sure one of us is going to the cemetery won't be me LOL. Any other thoughts
