Two common reasons that people fail to exit jibes planing even though they've entered with sufficient speed.

1. Flipping the sail way too late (as mentioned earlier). The tendency during a great entry carve is to enjoy the carve, when what you need to be doing is beginning the sail flip a half second after the nose of your board passes through downwind.* A successful planing exit is usually done on a broad reach, which means the entirety of the sail flip and catch needs to be completed long before the board is anywhere near on a beam reach in the new direction.

2. Handling rig sheet in two dimensions (in/out, forward back) as opposed to three (consciously apply downward pressure through the boom into the mast base) which prevents the tail from digging and bringing you to a halt.

*"a half second after the nose of your board passes downwind" is a broad generalization...every jibe is different. But I'd suggest trying to flip the sail much, much earlier than you currently are. Not a small incremental change, a large one. See what happens.

Flip early and flip fast. The bigger the sail the slower the flip. Compensate by throwing away the clew with your back hand to speed the rotation (push away with your front hand for a duck).

This is more of a problem with bigger sails in lighter winds (under 12 knots), but if you flip too "early", you will find that the board is going faster than the wind and you can't flip the sail. This is why you should be sheeting in (sail foot in line with the board) until the mid point of the gybe so you can reduce the drag on your rig as you hit the slower moving air. The is true with any gybe in any wind with any sail if you have good speed, but it is more pronounced with the big sails and slower speeds.

You flip the sail when board speed and wind speed are matched/neutral or a little past (wind helps flip the sail). However, if you wait too long then you loose too much speed and stall. It is different for every gybe and finding the "sweet" spot to flip takes thousands of gybes.

What Fox and Techno said. But (re Techno) whenever you flip, you've also got to be applying downward pressure through the rig during your carve entry. Keep your board's nose down.
