You know it can't be diagnosed with no details, observations, or test results to analyze. You could have a stretched timing chain, plugged exhaust, retarded ignition timing, dragging brake, tight universal joints, misfiring spark plugs, collapsed pickup screen in the gas tank, slipping transmission, two spark plug wires mixed up, or a carburetor problem. For all I know you could have a flat tire or someone put diesel fuel in the gas tank.
