Ok so today my car started having on off problems with turning off a couple secounds after starting, turn the key on and absolutely no power, radio turned off and reset itself while i was driving ( all radio presets reset when i turned on the key the first time but i put all them back and then later in the night it turned off when i was driving and reset ) and after there is no power when you turn the key i can turn it off and back on then it would start, light are flickering when I'm driving... i checked power cables everything is tight battery in it right now has plenty of power and even put a new one in just to check it was not the battery... and like i said it is on and off it did it through out the day but sometimes there were no problems at all... i am lost i have no idea what is causing this any info would help....
