well. if the engine runs alright while sitting there and not in gear i would suspect maybe the torque converter is locked up. only thing you can do about that without pulling the converter would be to rev it up real high and drop it in gear to try to break it loose

Do a vacuum check. http://www.theautoist.com/vacuum_guage.htm
My 318 poly was killing out when engaging any gear. After checking timing ( which could not be set by timing light without killing the motor ) and checking vacuum ( 10-15 ) I diagnosed jumped timing. Well it had not jumped, but the timing chain was stretched so bad it compromised the valve timing. A fresh chain cured our condition.

Too much cam and not enough convertor?

Try jacking the rear tires off the ground and engaging drive without touching the brake at idle and see if it dies.Gotta start somewhere:edgy:

Can he rev it up in park? Would not advise dropping it in gear at a high rpm. Might just be a timing or fuel problem. Think simple first. What if any were the events before this problem took place?
