Just bought a new E-tec 250 on new Ranger. During 2nd outing and 2nd or 3rd hour of operation the engine began losing power at 3000 RPM and then skipped lost power and died. All of this took 30 or so seconds. After this the engine would not crank. Would turn over but not crank. No buzzers as this happened. Engine did not crank the rest of the day. Just as if it ran out of gas but the gas line bubble was full. Took to dealer 2 days later. Dealer said engine runs fine, no error codes and cannot find a problem anywhere. Need some help. The dealer is taking to the lake tomorrow. Need to know what the problem is.
