Default MS won't power on sometimes?

Developed a new odd problem. Let my car sit for 4 days (snow / work) and went to start it tonight to drive some... No power to megasquirt. This is the second time its happened. Took it out, inside to the bench, stimulator.. took a few tries, but finally powered up and all is normal. Took it back outside, hooked it up, fired right up.

Anyone else experience this? Its hella cold outside, not sure if that has anything to do with it? Possible solder bridge or maybe some flux left on the board shorting something out?? Confused.

I've never heard of anyone having that problem. Did you clean your board with acetone when you finished it?

I tried cleaning it with 95% isopropanol which still wouldn't take any of the old flux off. Popped into my brothers work to grab some flux cleaner and came home with a can of "RITEOFF" defluxer. Thats some nasty ****, and it took the flux off the first spray, then I went back over it with the alcohol. Might have to take it out and check it all again just to be sure but I'm really worried. This could be a big problem and leave me stranded somewhere. :(
