Intermittent electrical problem--need help!

I recently bought a 1998 Voyager that has a baffling intermittent electrical problem.

Part of the time it drives like a champ but then the speedometer goes crazy, the engine dies for a millisecond--it sputters and then it takes off again--and the transmission goes into safe mode. It'll do this for awhile, then everything is okay again for awhile.

Any idea what's going on and how I can fix it? I'll sure appreciate your input

I'm not 100% familiar with the Voyager, but those symptoms sound awfully similar to a dying crank position sensor.

Thanks, Stealthee! I'm going to go check that out. :)

Thanks, Stealthee! I'm going to go check that out. :) That was not the problem I had a another van an changed the parts. Do you have any other thoughts of what it might be. Thank you for your time.

Thank you but that was not the problem any other thoughts of what might be wrong.

It's fixed! Turned out to be output speed sensor to the speedometer. I never thought that could cause so many problems.

If anyone wants to know, the sensor is a Standard product that I bought at Bumper to Bumper. It's an SC104 sensor.
