Problem with the electronics and limp mode? on track

[ZBW39]

I was on track this Friday and two things happened that I'm not sure what's causing it.

1. Oil temp was at about 240-250, I'm sure it's no where near 260. After exiting a corner, I saw the slip light flashes couple times, then suddenly the engine rev got cut down to 5000rpm for a good 2-3 seconds. After pumping the gas couple times it started to rev up again. Is the VDC causing this?

2. Laps later, at the same corner exit, the car behaves as if i let go of the gas pedal completely and starts lowering RPM, 6k, 5k, 4k, 3k, then to 2k!? The car is not responding even when I pump the gas couple times. So I drove off the track on to the dirt. Turn off the engine, start it back on. Then everything returns to normal.

Anybody have any inputs to the two issues I had above? Thanks.
