I thought I might some advice from the forum:

At our TMS race 2 weeks ago I was able to run a total of 1/4 of a lap in qualifying and that was it. Not fun. Here's the problem:

Car runs fine after intial start up however after it gets hot (temp 170+) it loses spark after 4000 rpm then dies. No spark and can't restart until it cools down.

We tried the following: replace coil, ignitor- no change. replace distributor- no change. relace TP switch and connector on harness- no change. Replace ECU- no change.

There are various error codes including: 7(TP sensor) 8(TD sensor) 14(IAC sensor)

I am running out of ideas at this point. Anybody have a similar experience or thoughts?
