Cutting out while driving

[blu1996powerstroke]

Hey guys please help. When im driving down the road at about 65 and faster when i accel more it starts to cut out. But if i go slow into the throttle it will cut out but not as bad. I have a ts and when i turn it to stock it really cuts out. So i turn the chip back up to 140hp its fine for awhile then will cut out again. I have unplugged the chip and now its fine its seems like.Until today it did it again.
Should i have it reburned? I have changed the cam shaft sensor, cleaned the fuel bowl and put new filter in. Also it idles really rough usually every couple starts. It has 195,xxx on it and never had any problems until now. Any ideas?
