2011 Ranger wouldn't start after stall on uphill grade
 

4.0L with manual trans 2011 Ranger Sport Ext. Cab 4-door wouldn't start after stalling on an uphill grade today. To be sure, I turned the key all the way off and all the dash lights came on as they should pre-start but turning the key to start made all the dash lights go out and nothing happens, no click, nothing, it's like dead. Luckily nobody was behind me so I popped the clutch in reverse and it started and didn't happened again but I was on level ground the other times I started it. I will do some more testing tomorrow to see if I can narrow down the cause and effect but in the meantime, I was wondering if anyone else has had this issue.

Or is there a sensor on the clutch or something that might be going bad?
