Help, washed under hood, can't keep car running.

Help, wash under hook, can't keep car running.
There is a big event here this week Crusin' the Coast, thousands of cars.
Of course I wanted to look good. So washed under the hood.
Not a good move, now when I start the car it runs for about one or two minutes, stumbles and shuts down. Let it sit a few minutes and it will start again but stumble and shut down.

I have blown all the electrical connections off with compress air.
Checked the distributor, its clean and dry.
I let is sit over night and it run about 4 minutes and shut down again. Which left me in the middle of intersection.

Any suggestions, I running a MSD 6 BTM and JMS chip every thing else electrical is stock.

Please help took a week off from work to take my car to the event!
