checked the charge on the batteries, there a little low , i'm charging them now. checked all connections, the bolts were tite, but i found the wire from the controler to the reverse switch was moving on the bolt, removed said bolt and found it was gauled, cleaned threads and re-installed , i remember that that connection was hot when it stopped running, it run's now, i think this will solve my problem!!! thanx for your input.
