Yes, I was going to say try jumpering the FPR with a paperclip after the stall to see if that remedies the problem. I have personally experienced the same symptoms you describe and it turned out to be my FPR. I replaced it and have put about 5,000 miles on my car and it has never stalled again.

Also the suggestion to check the duty cycle is great; will give you an indication if the on/off is working properly. If it's not, it can exacerbate other issues.
