tach,speedo, and gas gauge die for a second, randomly while driving

What is your question?

All gauges die for a split second then come back on, temp gauge not affected . it happens randomly while im driving or even just sitting still idling. truck power is not affected and no check engine light is on, recently changed all belts.

What makes this problem better or worse?

only noticed it on long drives

How long has your 1999 Toyota 4Runner had this problem?

few months, have only seen it happen about 5-6 times
