I have a 98 F150 4x4 with electric shift. this is a new problem, it dies in reverse, just dies like it stalled out. but starts right back up. and the four wheel drive wont engage usally I can hear the selenoid trying to engage but now no noise at all. and I noticed them both at about the same time when I was trying to pull a buddy from a ditch. I doubt they are related but I am lost on these new trucks with all the sensors and junk. any imput would be helpful.
