sounds like the time where the computer is supposed to take over (normal operating temp.) it doesn't have some parameter it's looking for. You need to have a graphable scanner hooked up to your vehicle and see what happens when it reaches normal temp.

check to see if your engine temp is -40F. if the temp sensor is open it will go to -40f
