Get the transmission scanned, cheap OBD scanner won't cut it.

If that light blinked you will have some codes stored, normally when codes pop up its because the tranny is slipping many times the Torque converter.

Most likely you have a damaged and/or corroded wiring harness. It's going to be intermittent until it fails completely. This usually requires someone with the right tools and experience to find and fix the problem. A good independent shop is your best bet, dealers don't often get problems like this.
