When I pulled it looked to be a slight burn mark on a white wire going to the turntable motor. I taped the wire rolled the sheet metal so it wont cut the wire again. Re installed it worked for about 6 minutes in 4 different uses. will it run if I unplug the motor? If it will that would prove it's the motor. Will it?
Diagnosing Panasonic microwave oven stoppages:
If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter, controller, magnetron, or a bad connection from one or the other.
If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.
If it stops after 7 seconds, it has a problem with the inverter.
If the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle.
Or see if this describes what's happening:
Put in time, push start and unit runs for 2 seconds, relay clicks, unit goes off. Cook time on display goes off and clock time comes back. Bad upper interlock switch and charred connector. If so, see:

It may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.
Due to the complexity and lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

Although your model number doesn't seem to show up, the NNS950-series units are powered by an high-voltage inverter. And yours has failed. While an inverter (switched-mode power supply) is more efficient from a power consumption standpoint, it is more complex, thus more statistically prone to fail. These should only be examined and worked on by someone who has the necessary technical qualifications. Seriously. Often the machine-soldered connections in a microwave inverter are too weak, so they eventually fail, especially if heat is high in the area. They sometimes fail catastrophically. When not catastrophically damaged, you may hear clicking or squealing and may smell an electrical odor, which is sometimes obscured by the cooling fan. Sometimes a whole new inverter is cheaper than the time and labor required to fix the old one. If a technician is willing and able to troubleshoot and repair the inverter to component level, it will may be expensive, but may be worth it, especially if he or she will resolder and reinforce connections as needed as part of a thorough repair. That could easily make your inverter beter than a new one! You might be able to get some verbal estimates if you call Panasonic-authorized appliance / microwave repair shops and ask then specifically about inverter component-level repair and simple inverter replacement costs for your exact model number.

because of high voltage circuit thats happend ,please check highvoltage circuit may be short circuit or any companent burntout. check magnetron and high voltage diodes etc.

In most cases, this is a problem with the inverter or a bad transfotmer. Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these. I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here: http://www2.panasonic.com/webapp/wcs/stores/servlet/vServiceLocator?storeId=15001

could it be that i didn't follow the manuel because i got it second hand or is it because something is wrong with it,and i have to get it fixed.
