Leah,
I suspect that the 12v or ground supply to the Aladdin and dash is seeing a spike or noise. As mentioned above, be sure all the ground connections on the terminal bars are tight in the electrical bay under the driver's position. Next, I would replace the 12V circuit breaker for the dash or Aladdin. It will be on the ignition bus bar fed by the large ignition solenoid in the electrical bay. If it were failing momentarily it could cause the problem you are seeing.
