As far as the possibility of vapor lock check the routing of you fuel lines and see if they have a heat shield on them. If not you can use a larger diameter hose split to rap around the fuel lines. Also you will want to check your fuel pressure. Low pressure with excessive heat will cause a vapor lock. Granted most mechanics will probably tell you vapor locks are not possible with Fuel Injection and they are right to a point. Vehicles with return lines will not vapor lock because the fuel is continually be circulated. However, in vehicles that don't have return lines as yours I believe is can vapor lock. I have come across about 3 vehicles that had vapor lock problems in the past 10 years, so as you can see it doesn't happen often but it does.
Also, if you have been running the tank dry and the engine shuts off, you could also damage the injectors.
You also said you weren't sure if engine light was on or not. Find out and if it is have codes pulled. Post the here.
Yes the Lucas and Seafoam are name brands. You may need to check your local parts stores, I know NAPA carries them both, at least the ones here were I live.
