Have you considered testing the ecu coolant temp sensor and checking/replacing ECU capacitors?

I have put fresh race gas in. Pulled the plugs out, cleaned all the earth points etc(has an old link plus). It ran fine for over an hour no issue. Then I went to take it for a drive last week and it is back to square one. It started off rough this time I turned it over and then decided to run fine again for 20mins again only to return to running rough.
