We replaced the battery in our P38 about a month ago after it died and it has been working fine since. The car has been sitting for a few days and I went to start my car today and it was completely dead. I got a jump and let the car run for about 45mins to charge the battery somewhat and then drove it around the block. When I started driving, something didn't feel right. I took my foot off the accelerator and the Range kept going, at about 10-12 miles per hour. The RPM's were a little higher than normal and I could still brake to stop the car, but it was basically as if the car was on cruise control at that speed- no stuck floor mat, pedal, etc anything like that.... I cut my route short and went back to park the car, and turned it off. I tried to start it up again and it would not, though the battery still had some charge. Two hours later and it is completely dead again. We have already replaced a fuel pump incase that becomes a recommendation, but does anybody have any wisdom on this very odd sounding problem? Thanks.
