instrument cluster malfunction

from 2 weeks i was in a car wash,when i finished washing my jeep,started the engine,it started normally but all the gauges like fuel indicator,rpm everything was going up and down randomly it lasted for 1 minute than everything became normal,but the check engine light that was on turned off(the code was p0455 evap system..)i drove it normally for 3 weeks(the check engine turned on again after 2 days same code p0455),than today i went to the gas station,when i tried to start the engine suddenly the gauges did the same thing but this time the engine didn't start,or start and turn off immediately,after 6 tries the engine started normally the gauges get back to normal but also the check engine light turned off,and i was using it for all the day and everything is normal now!!!

(P.S.:i don't know if this may caused this malfunction but from maybe 5 weeks the driver door panel was not working(power windows button,lock/unlock doors...)i've found that the red wire(+12v)was broken between the door and the body,i reconnected it isolate it using tape and mounted back the rubber between the door and the body)

i can't find what the problem,maybe it's a wire shortening and causing the pcm to reset i'm really confused...i'll be thankful any help or tips

Remove and clean out battery terminals at battery. That sounds like what happens when you have dirty terminals.
