I have a 1994 GMC 1500 5.7 TBI with 165000 on it. Today it randomly stalled out on me. My temp, volts and oil gauges were normal. My oil pressure usually idles low around 15. My truck just shut down so I shifted into neutral, and cranked it and it started but then died again after maybe 5 seconds. I pulled off and when I pressed the brake pedal it was locked up. When I cranked it the brake pedal would start to go down but the truck still wouldn't start. I gave it some gas and it finally turned back on and I had not service lights or codes. I have no idea what it could be????? Iv read the fuel pumps go bad on these pretty often. Any other ideas or thoughts on what it could be? Thanks
