replace the birdcage bearings. they could be corroded inside especially if they are bsb bearings. .004 should be replaced every year. swap to .008. they mite feel good now but when theyre hot and under load it could be a different story. i have seen this happen many many times

Check to make sure your driveshaft is not too long or in a bind in the yolk. If you run a ballspline, check to make sure the yolk is moving freely and doesnt have too much slop in it. If it has alot of play in it, it will bind under load.
