Use a known good distributor from a buddy, and make sure your plugs are gapped right.

Might be an ECU problem check the Chip in the ECU make sure its secured right

MSD stuff sucks, stock Honda ignition components are good for 350-400whp easily. Sounds like you are losing the tach signal which can be the Cam Angle sensor (in the distributor) has a bad wire, connection, or ground.

Did you buy a NEW distributor?
I thought he was pointing out a different issue related to the heat.

x2 check the distributor.
