1994 montero 3.5 dieing while driving
 

While driving my 94 3.5 montero for some time it dies. If I wate for apx. one hour it will start again, but the problem will reacure. I left it running in thr driveway for three hours with the lights and AC rinning and had no probolems, however when I begin driving it it will eventually stall????? the vehicle has 230000 miles and has been problem free till now.
