yesterday my truck shut down completely while driving at 45mph. Brakes lock up

What is your question?

My aspen has been shutting down on me for a few weeks now I would place it back in park and turn it back on again this will happen I come to lights, stop signs and etc. yesterday while heading to work coming across a bridge it cut off completely I had know brakes and once I was able to get the truck to stop. It never cut back on. I thought it ran out of gas because I was low that wasn't the issue. one person thinks I "jump time" whatever that due to fact it's cranking faster than normal.
