Just started up the camaro for the first time in about 2 months and had a nice surprise. Started it and ran for about 30 seconds and then died. Would not re-start. Let it sit for 10 minutes came back started right up. Ran for about 15 minutes, then the idle raised up to about 1300 rpm and stayed there. Shut it off. Tried to Start it up, would not start and the fuel gauge would not read. Waited 30 minutes, started it up, and drove it down the block, still idling at 1300 rpm. Went to the store, came out, started it up and idled fine. Gave it a short 2-3 blast car died. Oil pressure gauge didnt read. Waited 5 minutes, started it up, drove home, parked it all gauges now working. No Codes, nothing noticably unplugged. I am thinking a bad ground somewhere maybe, but before I go hunting, figured I would see if anyone else had a similar problem.
