Every other pole on my sub panel is dead. Positions #3, #4, #7, #8, #11, #12, etc do not deliver any power to the breakers. The breakers all have continuity and are in good order. The problem lays in the poles. The neutrals and grounds are not isolated and I have yet to fix this problem. The problem arose suddenly as half of my barn and my chicken house lost power overnight and have yet to get it back! Thanks for your help.

Either you one pole of your main breaker is bad or tripped. Or you have lost one line of your 240 feed.
If you have a voltmeter and are comfortable with doing this. measure the main feed. Measure each side to neutral. Each one should be 120 volts. If not you have a problem with the feed.
If you do have 120 on each one them try tripping the break off and then back on.
If this is a sub-pannel then go to the main and check it. If it connects directly to the meter then call the power company.
*I had a similar problem several years back with a new 200A Square D box. It turned out that the problem was in the main breaker. My problem was backwards, though...both sides were properly hot when ON, but when the main was thrown OFF, only one leg went dead. The other stayed hot.Square D rep said that 3/1000 breakers fail this way within the first ten throws.ZAP!
