2004 Hyundai Sonata Car stalls after rain?

2004 Hyundai Sonata 6 cyl Automatic 68000 miles

A few months ago my car starting feeling as if it were going to stall out while driving and had a hard time turning over while being started out of nowhere. During this time the check engine light came on. I let the car sit for about a week and only drove it when I had to. After about a week the car began to run like normal and the light went off. Until today! We had a real heavy rain here today that caused some minor flooding on the roads. I was a few blocks from my house and my car began behaving as it had a few months ago and then actually stalled out and the check engine light came on. I was able to get the car started after having some difficulty getting it to turn over and managed to get it home. I have it sitting in the driveway now. The last time this happened I had the car hooked to a diagnostic and the code P1372 came out. I looked online and it says this code means Segment Time Acquisition Incorrect. Could something have gotten wet that is causing my car to do this? I can't remember if it rained heavy the last time trhis happened. Also, I remember something scraping the bottom of my car a few weeks before this happened the first time, not sure if it could be related. Could something have punctured a hole somewhere beneath my car and would that cause it to do this.
