Bravada stalling and not starting

2003 Bravada AWD 4.2 I6

Well I was out on a road trip with the Bravada on Saturday and we drove it 80 miles without a problem. Stopped to get gas, started up fine but as I was pulling away from the pumps it stalled and the speedo and tach needles went crazy. I was able to put it in park and restart it. Vehicle drove home about 50 miles and we stopped again to get some things at the store. When we went to leave the store it would not start…..the engine would turn over but then everything would go dark (dash lights, warning lights) and the speedo and tach needles began to go crazy again. After about 10 minutes of playing with stuff it started. Got it home and inspected the battery terminals for corrosion, removed each terminal and they were fine. Once I reconnected the battery it would not start for 20min…..It acted like it did at the store parking lot, engine would turn over then everything went dead. Then I put the memory seat in position #1, and the vehicle started right up no problem. Throughout the day I had the seat on position #2. Very odd, but the needles acted up once before a few weeks ago. I started the vehicle and pushed the position #2 button and the needles went crazy but the vehicle was still running and not moving.

So I plan on taking it to the dealer on Monday, I am going to have the battery tested by them. Any ideas of what else can be causing this problem? Anyone ever hear of a problem like this??
