start viper at least once a month in winter with no problems. yesterday, tried starting with no luck. jump started it today, but only would stay running with slight gas pedal help. finally, viper started running on it's own. i left car running for a good 20 minutes and shut it down. after an hour or so, tried to restart,you guessed it,no luck. i keep a battery tender on it all winter. i believe battery is 4 years old(previous owner). has anyone gone through this?? read some previous posts;sounds like bad battery or maybe alarm reset. any opinions on what i'm going through??
