Is there a gas smell in your oil if so give it a complete oil change.

While Miguel's is an old post waiting for an engine to cool are signs of electrical breakdown, which is the coil works while cool and quits when it warms up and maybe the crankshaft sensor falls in the same category. I don't know where this was headed but there are Yuo Tube videos of repairing the main relay, pull open it and look at the solder joints checking for cracks.
