Car goes to idle at speed

I have a 91 civic hb with a swaped in sohc 1.6L ZC. At a stand still the engine runs fine, It idles and revs up to the rev limiter with not problem. Oh ya i race it on a oval track. At pace speed its fine with short bursts (30-50 km) When its go time i mash the gas it boggs and sputters and then goes to idle. ive tried to ease in to it, its ok but when it gets to a surtan speed? (no speedo) it goes to idle. i restart the car and all if fine. till its go time again. Any help would be great. Thanks

Optional Information:
Year: 1991
Make: Honda
Model: Civic hb
Engine: 1.6 ZC

Already Tried:

Your ECU needs a reading from the VSS in order to operate properly...
