Does it get really hot under the hood of your van? Is it possible to relocate the ignition module farther away from sources of heat? I believe this "brain" only controls the ignition but I could be wrong. If so you might want to replace the stock distrubutor with an aftermarket one like Accel. https://www.holley.com/brands/accel/
