INTERMITTANT PROBLEMS - COMPUTER MODULE?

1999 Pontiac Grand Prix • 120,000 miles

1. Intermittantly, "TEMP" light comes on and engine cuts in power. Temp Guage remains in normal range.
2. Intermittantly, "TRAC OFF" light comes on and tachometer needle drops to zero. Engine remains running normal with normal power.
3. Intermittantly, "TRAC OFF" light comes on and engine stalls.

*Each time after the engine is turned off and restarted, the problem clears and car runs fine until the next time and intermittant problem occurs.

Could be loose/bad/frayed connections or grounds.
