My 1994 pontiac grand prix was running fine , i

Not an expert by any means, but I had a similar problem.
Everything was fine until one morning (it was a bit chilly out in my defense) I used my remote starter to warm up the car before leaving.
I forgot I had used the remote and hit the brake to shift into drive. Engine stopped (obviously with no keys in it!). I thought I could just put the keys in and go, but ignition would not catch.
I've actually made that mistake a few times before, but that day, for the first time ever, it prevented the engine from starting for a good 2 hrs.
Really was no solution. I just let it sit and kept trying every 30m or so with both the key and remote starter. The remote starter finally got it going again and this time I followed the instructions (put key in and turned to "On" position).
Since then, it has started up as usual.
