I had the same problem. Here is what I did to get through it and start winning races.
You are most likely a big guy like me and can probably rep out a bunch of 450lbs squats and curl "the stack" with your hamstrings. Good news is these weights made you super powerful, a trait some cyclists never achieve. Bad news is you are loosing the power as your wheel comes off the pavement a couple of inches, not to mention you go anaerobic very quickly (a normal condition as larger muscles require more O2). Now for the best news, all can be fixed/retrained.
1. Try sprinting in your drops and make sure you bring your knees up and in rather than out. Hill sprinting on your hoods combined with a pedal stroke that brings your knees "out" will bring any wheel off the ground. With your knees in, you will drive even more power to your down stroke and traction to your rear tire. Keep your back near flat and glutes over the nose of your saddle.
2. Control your power! What you are doing is a "burn out" of types. You are throwing so much power at your drive train that it is "jumping or skipping along", sort of like an SS Camaro with a 457 engine, pop the clutch and the wheels spin out. Lay down your power strokes in the saddle first, get up to 22-25mph then explode out. Your leg speed (spin) will be so fast that your need to pull the pedal up will be compromised, thus encouraging a more fluid sprint. If you still skip your wheel, you are not going fast enough when you jump out of the saddle.
Sounds like you got what it takes to scare the heck out of some racers during a crit. Try doing some crit races in addition to your Tri work as this will also help you train your lactic and anaerobic thresholds.
