Although this sounds like a fuel delivery problem, I wouldn't jump to the conclusion that the problem is just the fuel pump. Here's a few other things to check.
1. Is the fue pump near the tank and lower than the tank? Electric pumps are better at pushing fuel than pulling it.
2. Does your fuel line run near enough to the exhaust to cause vapor lock (boiled fuel)?
3. Are your float levels set correctly? If the primary float is set too low, you could temporarily exhaust the fuel supply.
4. Is there a fuel filter between the tank and the fuel pump? This can sometimes make it difficult for the pump to draw fuel.

Good luck solving the problem.
