I have a 1996 Plymouth Grand Voyager. It hiccups. By this, I mean it loses all power for a fraction of a second. It is as if the battery and alternator had been removed for a fraction of a second. It may go a few hundred miles without doing this and it may do it several times in one mile. If this happens while stopped or going very slow, the motor will die and you will have no power steering. You can immediately shift to “neutral” and start the engine and it will run fine. When this happens while going fast, say 70 MPH on freeway in Cruise Control, the speedometer will head to zero, but before it gets there the engine will restart and everything will be back to normal except cruise control will be off. You cannot get back to cruise by pressing “resume”. You must first turn Cruise on, get to desired speed and press “Set”. Sometimes the “Check Engine” light will come on after one of these hiccups. It will go off after a start or two. It has a code 12 (Battery input to PCM disconnected during last 50 key starts) which stays stored. Sometimes, after the “Check Engine” light comes on , it will temporarily store either a code 13 or 54. I have had the Cam position sensor replaced, but I doubt the old one was defective. What could cause this? Thanks

Check to be positive that the wire connections are tight both at the battery and at the underhood fuse box.

Wildman has a good point, but you also may have a bad motor mount. I say this because I had a '70 Monte Carlo that had the same problem, and it drove me nuts! When the motor shifts just enough to leave the mount, it's no longer grounded properly and bye-bye power. Then the motor settles back into the mount since there is no more torque on it, and the problem is gone. An independant shop, not a dealer, was the place that finally figured out my problem after the Chevy dealer changed out all kinds of expensive junk.
There are other things that could cause it, like a bad connection at the fuse block, bad engine ground other than the one at the motor mount, (check your engine to frame ground cable. Could be corroded at either end just enough to cause the problem you describe.) and as with any electrical problem, try to keep track of exactly under what circumstances it's happening. Like when you hit a bump, when you goose the engine, if you engage a certain accessory, etc. This will help the shop do a better job of troubleshooting the problem.

Error code 12 means "no ignition reference pulses received by the ECM." This, of course, is what you should be getting with the engine not running. 55 means "end of codes". If it's all you get, then you have no "error" codes. Based on some of the other symptoms you describe, you may have a blocked catalytic converter, or some other blockage in the exhaust system. The back pressure will reduce the power to zero and it will die. You can check by disconnecting the exhaust temporarily and see if power returns. (Don't do it after 10 o'clock at night or you will annoy the neighbors.) If so, it's time for a trip to the local muffler shop, and it will lighten your wallet considerably. Don't even think about just eliminating the catalytic converters, if you do the O2 sensors won't send the right signals to the computer, and you will have a run rich/poor fuel problem.
