Acting up cold and working warm.
When it is acting up.
Check all electrical wiring and plug in and connections.
You are losing 12 volt feed or ground some place.
Get a good volt/ohm meter and good wiring diagram and start at battery and cable ends both + and - and work onto fuse box and threw ign switch and onto what ever is acting up.
