Just trying to help. Jeep dealer won't tell you what code means? My guess would be in the intake system. MAF sensor? Air intake leak? I don't think its the pos. sensors because your engine would not run (been there done that). Your throttle is cable driven?

1999 Jeep Grand Cherokee Laredo 8Cyl4.7L When when driving over 50 miles per hour will lose all power whats wrong?


When you say it loses power, do you mean electrical power or engine power ?
You would need to look at the fuse boxes for a loss of electrical power, and use a scanner or code reader to check the computer for trouble codes for a loss of engine power.

p0320 is-- ignition/dist, engine speed input curcuit malfunction. Check the two hoses on either side of the engine that go to the intake. Any kinks or cracks will give crank error. I beleive you have a bad crank sensor. not sending signal to pcm. crank sensor symtoms-- No RPM Signal to PCM . also check wires to crank sensor.
