My 2002 toyota tacoma starts great but after going about 5 or 10 miles down the road sometimes it will quit. I have to coast to a safe place and restart it. Sometimes it restarts the first time. Most of the time I have to let it sit 4 or 5 minutes and it starts. It is driving me crazy. I have put the higher grade of gas in it and same thing--stalling while going down the road or coming to a stop light.
