2001 Honda Odyssey Power Loss and Warning Lights

Recently, while driving on the highway (100km/h) I was greeted with the check engine light, and the TCS light, as well as a bucking/sputtering engine with power loss. Dropping back to about 80 km/h while pulling over, she returned to normal, but the lights remained. With the foot on the break and put it in gear, and allowing throttle, the van sputters and bucks, but is fine while idling. The TCS light comes on near 40 km/h.
