It sounds like you are losing power to the controller. Do me a favor. The fuse is in the fuse panel on the passenger side. I attached the wiring schematic below and highlighted the fuse.
If it is tight and in good condition, wiggle the wiring harness behind the dash to see if it causes things to stop.
If that checks good, locate the ground, which is a black wire, located behind the shifter. Inspect it as well.
Let me know what you find.
See pics below. Pic 3 shows the fuse to check.
