The vehicle listed above is a G20 conversion van. Recently the van has been losing electrical power randomly. This means when driving, it shuts off and for several seconds it has no power. After a few seconds the dash lights/blower motor etc., all come back on, and the van will start back up as if nothing happened. The problem seems to occur at low speeds when turning, coasting, or slowing down. does anyone know what could cause this or have any ideas? Thanks

It sounds like the ignition switch is going out or you have a loose connection to the battery. Here is a guide to help you fix the problem and I have included how to change out the ignition switch as well in the images below #67:
