Need Advise on electrical system

Me have a power commander, recently the FI red light is on and the rpm needle goes up and down, but when I killed the engine and restart it, everything is normal again, is this my instrument gauges cluster problem or my power commander problem?

tks.

not sure about the FI light but the guages could be messing up due to a week battery.

What year and what mods?
