The symptoms sound like a possible fuel pump. Did the check engine light come on when the problem started occurring? Did the shop say why it needs a fuel pump? Did they measure low fuel pressure?

the pump itself should cost you no more than 90 dollars and thats price with strainer, and depending on your tank it should be about 1-3hours to drop and replace it's not that bad I just changed my first one this weekend, I had similar issue and also changed the fuel filter at the same time, so it doesn't fail too soon after the change. How are your plugs? Oil level fine? I replaced almost everything and now it runs like new

I just had mine replaced last weekend. Car died - thought it was the battery. Replaced battery and it was still dead. Dealer said the fp was corroded. Fuel Pump (aftermarket) - $327 (was quoted $575 for authentic Jaguar pump) and $195 labor. This was on a 2002 S-Type 4.0 V8. I know this answer comes a year too late, but hopefully helpful to someone else in the future... :)

Ok, I know this is just about 2 years late so I know you probably got the problem taken care of. But your symptoms sounds just like mines. So by process of elimination, I began to suspect that it was the fuel pump and/or filter. Like you I had a high estimate to, from a place(Aamco) that has a payment plan but I needed half up front. So I got more estimates and the I got an estimate from a place that I like from past experience with them(BrakeMasters)for $425. Since BrakeMaster saved me before when I needed my power booster replaced, they saved me a couple of hundreds then and they did a great job now; car runs excellent. So if you get a high estimate, check around before you decide! By the way I have an 1996 Buick Lasbre, the mechanic told me it looked like the original part because that company have not been around since the late 90's.
