so I was driving my truck one day and pulled up to the gas station to the fuel pump..didn't pump gas or anything..just parked at pumps in shade...truck sat there maybe 30 mins or so...when i went to leave..the truck just went click...couldn't get it to start..it acted like it had a dead battery...but all my lights were bright as ever...so then i thought starter...so anyways I rolled truck backwards and popped the clutch and it started right up. So while driving the truck home it started getting high oil pressure..but wasn't smoking or making any unusual sounds...ran like normal...but I have replaced starter solenoid on inner driver fender, starter, battery. And the truck is still doing same thing. Can someone try and lead me to my problem. Thanks in advance
