I just wanted to update this post from the old forum with the fix.  Ron's post hit it on the head. It turns out it was the magnetron thermal cutout that was going bad. Ron you know your sh*t!  I actually took this to a repair guys shop and somehow between the drive from my home and when the guy was checking it out it started working again(the cutout must of closed). He microwaved a bowl of water repeatedly for several days and it worked in front of me when I picked it up.  Brought it back to my house and it went dead again after installing it and running.  So finally he came out again and discovered it was the thermal cutout and then replaced it.  Been about a week and a half and been working great.

A little strange problem with my microwave oven.  After my wife had used the microwave oven without incident I put a plate of food in and just after a few seconds of microwaving the microwave just went dead( no lights on display, microwave light out, vent/light not working).  After un plugging and repluggin a few times display comes on again but as soon as I try microwaving it just goes dead.  Went away for weekend and came back still lifeless. Then a day later the display just comes back on. Try running vent and light and they work without fail. However, run the microwave and it goes out.  The display will just resurrect itself and come back a little quicker now but once just opening the door just turned it all off too.  The outlet seems to be fine when using other appliances. There is not metal in microwave, no arcing.  Anyone have any ideas. 
thanks,
Shaam

Shaam, it's possible you might have a magnetron thermal cutout going bad, under normal operation the cutout remains closed.  At high heat this cutout will open causing the oven to shut down.  This mag thermal cutout is wired across the nuetral leg of power to the board connector....therefore the board will go dead but the vent fan and lights would still operate if this thermal cutout were to open.  This is just one possibility.   This cutout is located above the leads to the magnetron...I'm sure some other techs will have some other ideas...Ron
