The Mom's Mobile is having an indermediate driveablity issue. About 30 or 45 minutes after warm up the car will loose power and begin to (intake) back fire.

It does this for less than a minute until the check engine light comes on and the computer goes into back-up mode, then it clears up and runs fine although the light stays on. Upon key off and restart the light will stay out until this happens again.

I looked up this code on an unconfirmed source and it vaguely states, "defective or malfunctioning fuel supply system". Can someone give me a better description of code 43 and perhaps a troubleshooting procedure.
